@AllisonMosley I'm probably the wrong person to ask on this topic. I did everything possible to save Jengo. Everything I could think of. While I don't regret why I did it... it haunts me that I let him suffer longer than I should have. Why did I do that? Because I/we loved him very much. He was absolutely part of the family. We were shattered without him. Crushed. In retrospect... I should have let him go earlier. As some say... they'll tell us, but I wasn't listening to him. I was listening to us. I sorta regret that now.
We tried Phenobarbital, which worked great till it didn't. It finally hit his kidneys. Then we switched him to potassium bromide, I think. It settled his kidneys, but his anxiety went off the chart. I kept telling myself he'd get over it. That was mistake.
I don't envy the choice you're facing, but I'll also never judge you for the one you make. Clarity is something I didn't have going through it. My thoughts are with you.
I don't regret one second that we had Jengo... beginning to end. Our love for him is why we have 2 more (6 more temporarily till the puppies leave). We find ourselves comparing the pups to Jengo, other Basenjis to Jengo, etc. I wouldn't be showing a Basenji if not for Jengo.
My point is... as hard as this is stay strong and focused... for your dog. Stay focused on your dog and not emotions like I did. Do what your dog is telling you... as fricking hard as that is. One of the hardest things I've ever had to do.
I'm sorry if I'm veering off course from your initial treatment question.
