First off, welcome to the forums. I hate that this has to be the topic of your first post, but I hope that you stick around even after this situation is resolved.
If this continues being an issue, and the vet really wants to have the quality of life conversation I would have it. Ask him/her to educate you on what kind of issues your BP is going to have and what ALL your options are. Sometimes I think vets suggest euthanizing because there's a concern that the owner won't want to pay what it'll cost to treat, so make sure you ask what all the options are. At the end of the day, no one wants to euthanize a pet, its sad regardless of the type of animal. I very rarely have to, but have had to euthanize tropical fish for one reason or another, and even something as small as that hurts my heart to see it go.
Sometimes, euthanizing is the best option, but again I would want to know what every options is outside of that. Once you've reviewed all your options with the vet, then unfortunately it's up to you to make that choice. Put the needs of your pet first, and even if it's not the choice you want to make, make the call that's best for Ziti.
