- *Nutritional deficiencies* - Cat food is often lower in protein and other essential nutrients that dogs need, so eating too much of it can lead to deficiencies.
- *Weight gain* - Cat food is typically higher in calories than dog food, so dogs who eat it may gain weight.
- *Gastrointestinal upset* - Eating cat food can cause digestive problems such as vomiting, diarrhoea and constipation in dogs.
Therefore, as a general rule, it is not recommended to allow dogs to eat cat food on a regular basis.
