my poor pup recently had an emergency spay due to pyometra and she wont eat! we have gotten her to eat tiny amounts 2 times in the past 3 weeks she is basically skin and bones. over a thousand dollars on vet visits and just more and more medicine but she refuses food. today i was able to get her to eat a bit of bread and peanut butter. i can see that shes starving and wants food but anytime she smells it she makes a face and walks away. shes starting to have difficulty standing and walking. any advice or ideas that can help her ?
