this same thing happened to our 14 yr old dog...4 years ago. The vet gave him a cortisone shot, thought it was a neurological issue. He wanted to do a brain scan to check it out, and could possibly lead to brain surgery, but no guarantees that this would help. Our dog was physically healthy and this could add _?_?_? time to his life.....
after a very tough discussion with my husband (who got our beloved Harley during his sr year of college) We decided to put him down. We took him home, had a few hours with him, and our kids. But Harley could no longer walk, drink, etc. We couldn't let him be miserable. Our whole family was crying.
My husband and I took him to the vet to be put down, let Harley fall asleep in our arms (left the room for the actual 'event') from a sedative. We have pleasant memories of our Harley. My husband did have dreams about Harley's head on his arm for weeks after.
That was a Tuesday, and by that Saturday, we added our yellow lab, Lucy.
She has brought so much joy to our life. Harley was a black lab. We wanted the opposite of him as to not "replace" him. My husband still has the "Harley Davidson" tag that Harley wore on his collar, he keeps it on his keychain.
As difficult as this experience was, we know that Harley is in a better place
we feel like we did the right thing so he wouldn't have to suffer. He had lived a good life and gave us many years of joy.
My heart goes out to you....losing a pet is really hard. Some people don't get another dog right away, but we did what was right for our family. My prayers are with you!
