We cook food for our dogs because dog food in cans sometimes are not available. We feed our puppy with dog food so we have experienced that problem. That's why when the puppy becomes an adult dog, we feed it with cooked food - boiled pork, boiled or fried fish, boiled or fried chicken, even beef sometimes. Late last year, one of our 3 dogs exhibited something odd. Pipoy is a pug so it is noticeable when his face gets swollen. We were very worried until we had contacted the vet to say that it might have been caused by food allergy. We brought Pipoy to the clinic. It's funny because when we arrived, the symptom was gone. But the diagnosis continued and chicken was suspected to be the culprit. So now chicken is taboo for Pipoy although our 2 other dogs are still being fed with chicken.
