How to prevent dogs from eating cat food

If your dog has made a habit out of stealing a few bites from your cat’s food bowl, there are a few tricks you can try to discourage this behaviour.

Feeding your cat and your dog in separate rooms will help put some distance between the dog and their newfound love for cat food.

However, this is not appropriate for older cats, or those with arthritis. Installing a crate for your cat can also help them have some peace and during their meal while keeping canine housemates at distance.
