Why is my German Shepherd losing weight with normal appetite and brown fur?

Updated on September 23rd, 2025

Pet's info: Dog | German Shepherd | Male | unneutered | 6 years and 1 month old

My all-black German Shephard has lost some weight but his appetite has not changed. Our vet also said he has a copper deficiency as some of his hair has turned brown but his parents were black and tan so we just thought it was because of that. I was just wondering why he might have lost weight and a second opinion on his copper deficiency as I read that too much copper can be very harmful to dogs.

There are many different reasons a dog can lose weight and many digestion issues can cause poor coat quality and colour due to reduced absorption of many nutrients. Try feeding a high quality skin diet balanced for optimal supplement for healthy skin and monitor improvement over 4-6 weeks. Royal canin skin care or German shepherd diet would be preferred options. A blood test and assessment for pancreatic function may also need to be considered
