I have a 9 year old German Shepherd/Border Collie mix. Yesterday she didn't eat at all, she started to seem very lethargic and stopped drinking water. Today her symptoms seemed to just progress to the point where she seems weak when walking. I started to syringe feed her liquids and she kept it down and she was able to go outside to urinate. Upon coming back inside I noticed that she just plopped right back down and on the ground where she laid I noticed that she had some very thick, brown, fishy smelling discharge ( which is what I assume she urinated ). She seems warm to touch, and increasingly lethargic. I called a vet and they will be coming to our home to evaluate her tomorrow afternoon, but I'm curious if anyone has any idea what might be wrong. I'm incredibly worried and any help would be greatly appreciated. Thank you.
