Have your dog checked for tumors - ultrasound will reveal if there are problems. I lost my little 4 lb 3-1/2 year old Yorkie over the weekend. He was doing fine one day and the next day I found him almost catatonic. Rushed him to the pet emergency facility and they could only do so much there. I took him to a pet hospital and they took an ultrasound and he had a large tumor in his bladder that had spread to his prostate and surrounding lymph nodes. It was inoperable. I held him for almost 3 hours and told him what a good boy he was and how much I loved him. He passed quietly with his head nestled under my chin. I sure do miss the little guy. He was such a joy.
Oh gosh, my condolences. Cancer is such a scourge. I didn’t want to mention that, but it’s always a possibility.
How terrible for you. You have my sympathy.
OH NO. I am so sorry. Your post made me cry, but I will do what you suggest for my little girl.
