My senior dog is losing weight. What food helps him gain weight?
First of all, you should get Zorro checked by your regular vet, as he has lost a lot of weight. Weight loss could be due to liver or kidney disease but it is also commonly seen in diabetes, hormonal disfunction or even tumors. Zorro should have a blood and urine test done first (and possibly abdominal scan and chest x-ray), and if the results are negative, you can think to increase the calories intake. Giving food for young, active/working dogs is one of the option. But if Zorro, for example suffers from diabetes, he will continue losing weight regardless what he is feed until the diabetes gets under control.
