I have an 8 year old Rott that will only eat people food, sleeps ALL day, is losing weight, and breathes like an old man. Up until 1 1\2 weeks ago she was just fine, this came on suddenly. She is also very weak and has a hard time getting up and walking down stairs. Do you have any idea what is wrong? I thought it was a cold but now I'm not so sure.
Optional Information:
Age: 8; Female; Breed: Rottweiler
Already Tried:
just keeping her warm and letting her sleep
