Sorry for your loss. Had to have emergency on 16 year old granny Chihuahua. Cancer of her uterus. She is recouping now as we speak. I was sure they were going to open her up and say the cancer was rampant , but thankfully it wasn’t. They think they got it all. Vet said she was the most healthy 16 y.o. she had ever seen. She still even likes to play for a short while at any rate. Can hardly see and hearing seems to be gone now as well. So it probably won’t be much longer that I get to enjoy her. But when she does pass I will know she had a good long wonderful life.
I’m glad your Chihuahua is recovering and will have many more days of love!
