Thank you all for your kinds words, and for sharing your stories.
I guess the question of whether or not to let the surviving pet see is very very tough to answer. I may never know if I did the right thing for Dexter, but I do think he understands. And that makes me feel better.
I've thought about getting Dexter another buddy, but I just don't think it's the right thing for him. He is 11 years old, and I think he and I will have our alone time now. He was the "second" dog and never got to have his alone time. We've been having lots of fun, going for rides, and playing, but he still seems a little lost. And I know he will for a while. I think another buddy (especially a pesky puppy) might offend him. But then again, I don't know--he still acts like a puppy himself!
If something (another puppy or dog) were to "land right in my lap", I'd consider it, but it would have to be the scenario where "Ginger sent it to us". I know that sounds a little goofy, but that is the way it would have to be. And even if we were to get a puppy/dog, and Dexter lives 2 or 3+ more years, I don't want to watch another pet grieve for their lost friend. It is so hard.... I know it IS life, but geez... it's heartbreaking. I've always said that 2 boxers are the only thing better than A boxer, but I don't even know if I'll ever have 2 again. I just don't know... it's too soon to think about, I guess.
I do think playtime with another dog (boxer) would be good... I may try to post something in the "boxer bash" forum, but I don't expect much luck finding anyone local. I may even ask my vet if Dexter could play with his boxer someday. (Good idea!!)
But again, thanks to you all for your well wishes. I'm so glad I have my friends at Boxerworld to talk to. We'll get through this!
