Can Dogs Eat Tuna?
Can Dogs Eat Tuna?
1 min read
Tuna is better known as the ultimate cat treat, but dogs can also be attracted to the powerful smell of this popular pantry staple. So, if your dog is begging for a bite, here are a few things you should know before caving in to those puppy eyes. Can dogs eat tuna? Opinions differ when it comes to the question ‘can dogs eat tuna’. Tuna is safely used as an ingredient in many balanced dog foods, but when it comes to feeding extra tuna as a treat, there’s some conflicting advice out there. Some experts don’t hesitate to recommend this fish, while others advise against adding extra tuna to your dog’s menu. There are definitely reasons to be cautious with tuna, but when fed very occasionally in moderation, tuna is unlikely to cause health issues for your dog. Every dog is different, so if you want to feed a dog tuna it’s important to offer very small quantities at first, to see how your dog reacts. Is tuna good for dogs? Tuna is rich in protein, minerals and vitamins – all important nutrients for a dog’s health and wellbeing. It also contains Omega 3 fatty acids which are good for the health of the skin, coat and cardiovascular system. This means that tuna is useful in some dog foods as a source of various nutrients. When it comes to feeding extra tuna as a treat, there’s no need to give it for nutritional value. If you feed your dog complete and balanced dog food, they should get all the nutrients they need from that. Why is tuna sometimes considered harmful to dogs?

Why Do Dogs Eat Grass and Dirt?
1 min read
If your dog keeps eating grass or dirt, there’s no need to worry - this isn’t uncommon behaviour by any means, even though it might seem quite strange. If you have a four-legged friend in your life, chances are that you’ve caught them grazing once or twice on their daily constitutional. For pups that do this, owners often wonder, why do dogs eat grass exactly? Over the years there’s been numerous old wife’s tales about the behaviour, with many believing it’s for the purpose of self-medicating – but is this true? Why do dogs eat grass? Dogs eating grass is very common, but there’s actually little evidence to tell us why they do it. Behaviourists and veterinarians have been perplexed by the behaviour for years, but some of their theories include: 1. Self-medicating It’s likely that you’ve heard this one for an answer to why dogs eat grass. It’s widely believed by dog owners that if a dog feels nauseous, they’ll eat grass to make themselves vomit and then feel better. However, this still remains a theory. In fact, dogs vomiting after ingesting grass is quite rare, with less than 25 percent doing this and only a further 10 percent displaying signs of illness beforehand. 2. They like the taste of it Another reasoning could be because they simply like the taste of it. Dogs are descended from wolves and as such, they’re natural scavengers – meaning that they might be grazing in your back garden as an opportunity to forage. Additionally, some veterinarians have suggested that dogs might eat grass to make up for nutritional deficiencies in their diet. This is supported by a study outlined by Fetch by Web MD, with a dog who ate grass every single day for seven years, then the moment it was switched to a high-fibre diet, it stopped. However, there’s currently not enough studies on the topic to satiate if this is the reason behind why do dogs eat grass or not. 3. Eating grass due to boredom If you’re just letting your dog out into the garden to play by themselves and not offering enough mental and physical stimulation, then your dog eating grass may be because of boredom. To try and reduce the behaviour, make sure you’re giving your pup enough opportunities to exercise, and get some toys for them to play with in the garden too. Puzzle games are excellent for mental stimulation, chew toys are great for boredom-busting and your dog is bound to love a ball game too! 4. Dogs might need grass in their diet Another explanation for why do dogs eat grass could be down to the way they’ve evolved. This theory relates to the fact that wild canids eat all of an animal when they catch it. The animals that wild canids – your dog’s ancestors – would catch and eat were usually herbivores. This means that when the wild canids ate these animals, they might also have ended up eating a lot of grass and plants that were in the intestines of their prey. Wild canids such as foxes have also been known to eat certain berries and other plant material, supporting the idea that dogs eat grass because it’s a part of their normal diet.

Why are dogs so loyal?
Why are dogs so loyal?
1 min read
There is no denying that one of your dog’s most defining traits is their loyalty. This loyalty can be overwhelming and humbling, and has often been cited as an example of what human beings can learn from dogs. But life lessons aside, where does your dog’s loyalty come from? Yes, you feed them and play with them and have your deep sense of love for them, but does that fully explain the depth of emotion they hold for you? In this article, we explore loyal dogs, why dogs are loyal and when that loyalty may need to be contained. Are dogs really loyal? The concept of a loyal dog has been peddled so much in today’s media and advertisements that you can be forgiven for questioning its premise: are dogs really loyal? Let us get the question out of the way: yes, they really are. The stories of dogs who wait endlessly for their owners or who are overjoyed to greet them years later are not made up. You can see the evidence in your dog, who is delighted when you return home from work and greets you as if they haven’t seen you in weeks. If that is not deep loyalty, we do not know what is. So, what makes a loyal dog? There are several theories on where your dog’s loyalty comes from and why it is so deep. Here we explore a few of the explanations for your dog’s loyalty, ranked from simple to intriguing. The simple explanation: you give them food The simplest explanation for your dog’s loyalty is that you give them food and shelter. Your dog is grateful to you for the essentials of life that you provide and so is loyal to you. There is a scientific basis for this: domestic dogs are descended from wolves, which man once took in and tamed with shelter and food in return for them acting as guard dogs. This reciprocal relationship remains in your dog’s genes and their loyalty is a by-product of it. Of course, this would mean that loyal dogs adore anyone who feeds them. This is also largely true, as dogs do tend to grow more attached to the family member that gives them their food. But it is not the only explanation. Looking to dog psychology for answers: dogs are pack animals Dogs are also pack animals and long to belong to a pack. They are much like humans in that way – it is said that no man is an island and the same can be said for a dog. To your loyal dog, your family is their pack and they have adopted you as their own. Loyalty in a pack is crucial. In order for a pack to survive in the wild, their members must work together to overcome dangers. Trusting, co-operating and putting the pack’s interests first are all a natural part of surviving. It would explain why dogs often put their own lives in danger to protect their owners; their pack instincts require it of them. But that cannot explain everything. After all, your dog still loves you when you return from a long vacation and you have not been feeding them during that time. And what about Hachito, the loyal dog who used to greet his owner each day at the train station after work – and continued to wait for him for nine years after he died? Neither pack instincts nor reciprocal relationships can explain that. But something else might. The intriguing explanation: dogs may love In 2005, Science Direct held an experiment on canine behaviour, where they presented dogs with their owner’s scent, a scent of a stranger and the scent of food. Brain scans were taken of the dog as they approached each scent. The study hypothesised that since smell is so important to dogs, it would be the best way to understand how canine brains work. They were right. Not only did dogs react more strongly to the scent of their owners, the part of the brain associated with enjoyment and positive emotions lit up when they were given their owner’s scent. Your loyal dog does recognise you. The same patterns in humans would usually be associated with love. In another experiment, a dog was allowed to watch a stranger be rude to their owner. When the dog was then allowed to interact with the stranger and the owner, the dog actively snubbed the stranger. If that is not loyalty, we do not know what is.

Wet or dry cat food?
Wet or dry cat food?

When it comes to choosing wet or dry cat food, the information can be overwhelming. Conflicting information and the sheer amount of choice on offer can all make choosing your cat’s diet seem difficult. Go back to the basics with your cat’s diet in this article to learn all about the benefits and drawbacks of both wet or dry cat food, so you can make the right choice for your pet. What do cats need in their diet? Every cat requires a total of 41 essential micronutrients from their food each day – whether it be from wet or dry cat food. These micronutrients are ‘essential’ because they cannot be manufactured in the body, and they are necessary for normal, healthy function. Cats are obligate carnivores who need to eat meat, and as such they can’t be fed a vegetarian diet without developing malnutrition problems. A proportion of their daily nutrients must come from animal sources, specifically the amino acids taurine and arginine, the fatty acid arachidonic acid, and pre-formed vitamin A. What do cats like in their food? Just like humans, when it comes to food, cats enjoy something tasty! Although they have far fewer taste buds than other animals—a mere 475 to dogs’ 1,700—they do have some interesting appetite quirks. A cat’s sensitivity to bitter tastes is 400 times greater than that of a dog’s, but they lack the taste buds to be able to enjoy sweet flavours. Texture and shape are also important factors for cats when it comes to their kibble. Cats’ sense of smell is superb, and is an essential part of appealing to their appetite. Food odours give pleasure, enhance enjoyment of food, and provide your cat with their own sense of nutritional information.

Puppy Sleeping Arrangements
Puppy Sleeping Arrangements
1 min read
When you get a new puppy figuring out their sleeping arrangements can be difficult. Find out what the best options for puppy beds are and if you really should let them sleep in your bed with you. With all that playing, your puppy will need lots of rest, so appropriate puppy sleeping arrangements should be made. Avoid giving into temptation and allowing your new pup to sleep on your bed, even on the first night with your new puppy. It will quickly become a habit that you later might regret when they won’t be able to sleep alone! It’s best to make them a comfy nest that they can call their own, where they can be snug at puppy bedtime. If you’re using a puppy crate then a cosy bed can be put inside, with layers of newspaper underneath to soak up any spilled water or wee accidents. The puppy crate, or bed (if you’re using a bed on its own), should be placed in a quiet corner, somewhere where you can keep an eye on your puppy when they are inside, and out of the way of kids playing and general noise, so they can have a good rest. A corner of the kitchen will allow easy mopping up of any spills. If you’re placing the puppy crate on the floor elsewhere on carpet, some newspaper or (chew-proof!) waterproof pads underneath is a good idea. If you already have other dogs in the house, then placing your puppy’s crate alongside their sleeping area will give your new pup some reassuring company. However, if your existing pets are wary or upset about their new housemate, then it’s better to keep puppy’s sleeping arrangements separate, until they’re used to each other and are happy snuggling up or playing. What to expect on the first night home with your puppy On arrival in their new home, your puppy may take a while to settle in. This is likely to have been the first time they have been away from mum and their siblings. During the day, the activities of playing and sleeping might mean your puppy has been distracted and has not noticed that his previous doggy family are no longer around. When it comes to night-time though, it's dark and long, and it’s normal that your pup may get upset when you spend your first night with your new puppy. As a general rule, puppy first nights can be tricky – but they’re easier to navigate if you have some idea of what to expect.

How to Help Your Constipated Cat
1 min read
Although cat constipation is a fairly common problem, the causes and symptoms can be wildly different from one cat to the next. Discover what you need to know about this condition to help treat it quickly and prevent it from making sudden appearances into your cat’s life. If you suspect your cat is constipated, you’re no doubt eager to figure out what has caused it and how you can provide some relief to your beloved cat. In this article, we look at the essential information you need, from early symptoms all the way to veterinary cat constipation treatment and ways you can prevent the discomfort to help your cat get back to their usual happy self. Cat constipation symptoms A cat who hasn’t produced stools for more than 24 hours is likely to be suffering from cat constipation. However, sometimes owners might not be up-to-date with their cat’s bathroom routine as some felines are known to like going to the toilet outdoors as well. Therefore you might not notice the infrequency of their toilet habit straight away. These are some of the other symptoms of cat constipation you may want to keep an eye on: • Tense abdomen • Hard, dry, small stools • Straining which can be mistaken by owners as difficulty urinating sometimes • Lack of appetite (occasionally) • Hunched posture

Harmful Substances and Poisonous Foods for Cats
Harmful Substances and Poisonous Foods for Cats
1 min read
Your cat’s sense of exploration is one of the things that makes them so precious to you, but it sometimes means you have to keep an eye out for things that can harm them, too. There are many harmful substances and poisonous foods for cats that your feline friend might come across in their lifetime, so it’s important that you know which to keep out of their reach in the home. Your cat’s natural curiosity leads them to explore non-stop; whether they’re roaming the great outdoors or climbing into all the nooks and crannies of your house, there’s no knowing what they’ll find on their next adventure. Around the home and in the garden there are poisonous foods for cats and non-food substances, including plants, which could be potentially dangerous to your feline friend. Some of these are obvious, but others look completely innocent. For example, your cat might like the look of the snack you just ate or the medicine you take, but these things – while causing no harm to us – might be poisonous foods for cats, and in some case they could be life-threatening. Many chemicals that are routinely used around the house, such as bathroom cleaners, can also be harmful if your curious cat gets their paws on a bottle.

Feeding Your Cat During Pregnancy
Feeding Your Cat During Pregnancy
1 min read
Pregnancy is both wonderful and wonderfully tiring, for you and your pet. One important thing you can do to help your mum-to-be is to give her the nutritional support she needs. Choosing the right feeding plan during pregnancy will ensure that she grows fit kittens, and has the strength to handle birth and nursing her newborns. The adult food you normally give your cat is great for her everyday diet, but it won’t provide the extra boost she’ll need when expecting. For a happy mum and healthy kittens, pick a formula that will meet her new requirements. A high-quality kitten food will provide all the necessary nutrients when feeding your pregnant cat. Start weaning her onto it from mating until a few weeks after giving birth, to keep her strong and give her the energy she needs to support her new kittens. Pregnant cats need higher amounts of calories and protein, both of which can be found in high-quality kitten food. Switching mum onto a kitten food will also help her litter, as they’ll be able to copy her and try some of her solid food as they wean off her milk. We have a selection of products to suit a variety of diets that you can try.

Feeding Your Adult Dog
Feeding Your Adult Dog
1 min read
With your tiny puppy now all grown up, it’s time to say “goodbye” to puppy formula and “hello” to adult dog food. This usually happens at about 12 months old for small breeds, and around 24 months for giant breeds. Just like people, every dog will have a different requirement when it comes to food intake. Factors such as life stage, activity levels, breed, size and age can all affect the ideal portion size, and your dog’s needs will change during the course of their life. If you’re not sure how much food to feed your dog and what diet to pick, here are some handy tips from our Pet Care Team. How often to feed a dog? Our Pet Care team is often asked: “how often should I feed my dog?” Many adult dogs are fed twice a day – equivalently breakfast and dinner. However, a puppy should be fed more frequently throughout the day, with three to four (or more frequently when they are very young) meals recommended until at least six months of age. Some smaller breed dogs will also benefit from three smaller meals. Owners of larger breed dogs sometimes opt to feed one meal a day, however if your pet has a tendency to bolt their food, they may be better off with two smaller meals, rather than one big one. Bolting a lot of food at once can lead to gastrointestinal problems. If you’re not sure how often to feed your dog, speak to your veterinary practice.
