Syn is a cutie! You are correct that there are common health issues specific to certain breeds of dogs, but that is found in purebred dogs due to inbreeding. She is a mixed breed, so there aren't really any breed specific health issues for her but that doesn't mean she isn't susceptible to health issues such as diabetes, hypothyroidism, or cancer among others. It certainly is possible she could be suffering from hypothyroidism if she is gaining weight, but that's usually occurring in middle aged dogs (4-10 years of age). It could be that she is getting too much food and not enough exercise leading to her weight gain. I would have her seen by a vet for this weight gain. The vet can do blood tests to determine if she is suffering from hypothyroidism, and can treat her if she does have it. If she is medically normal, then the vet can discuss a diet and exercise program for her. I hope this helps!
