Actually, I think it shows how responsible you're being. Kudos to you.
You're military, right? The Vets on base are pretty inexpensive (comparatively). Will you ever go to a base that doesn't have full service vet care? My suggestion is to see if you can take the dog in for a full exam before you make any concrete decisions. Explain to them your situation. They *should* work with you on this. Take the dog's vet record with you. From there, find out how much it would cost to take care of these heath issues. Then, call around & find out how much it is off base. To be even more proactive, you could try calling Vets in prospective areas you might be stationed during the remainder of the dog's life. Then, ask yourself - do I have the time to dedicate to this? Will I be able to afford this if we move to an expensive area, with no on full service on base clinic? Do I forsee a situation where I wouldn't be able to handle this -- such as if the hubby gets deployed? If you find yourself questioning an answer, it's not wrong to turn down the opportunity. It makes you even more responsible. On the other hand, if you don't forsee any problems, then God bless your soul!
Good luck in your decision. I wish you & the sweet doggie in question the very best luck!
All the best,
Catherine
