I have a 13 year old weimaraner. Had his nuts his whole life.
About 5 months ago they started swelling, took him in and turns out he had testicular cancer.
Removed testicles, cancer did not spread thankfully (they said it was 'slow moving' kind).
Since the surgery, he has not been the same dog.
He has NO DRIVE. He has NO MOTIVATION. He sleeps ALL DAY.
I know he's old and has some arthritis in his hips but I think the zero testosterone is really hosing him.
Shoulda seen the look on the vet's face when I asked about hormone replacement therapy.
My dog is depressed. He's gained ~12 lbs, gone from 80-82 lbs to 93-95 lbs. All fat, he feels like mush now when he used to be hard as a rock.
HRT?? He doesn't even chase poon anymore or hump anything.
