Sorry about my grammar, but I'm just desperate to find a way to resolve my dog's sickness if ever there is. He is half Japanese Spitz and Labrador and always loves to eat even the snacks I eat. He used to consume every food in his bowl, but these last few days, there's always something left. He also looks gloomy and stress.
It all started after my adopted puppy died, she used to be his playmate. Please help me

Dogs can suffer fromd epression just like humans can. If he lost his best mate, he can be feeling the heartache from this. A little extra love and snuggles can go a long way with a dog and depression. Are you thinking about getting another dog?

If he lost his playmate he is going too be a bit sadand deppressed it isn't a sickness if he isn't eating all his food.are you getting another dog? If so this may make him feel better if he has another dog to play with.just make sure you are there to comfort him talk to him and play with him.
