Well ... I have no "shortage of Plan B's!!
And while you did look at your local rescues and they had nothing "available" for you ... "Then??" It does not mean they won't, "now, tomorrow or six months from now??? If they are successful at what they do??? They get dog's all the time. And rescues always need "Foster's."
And as such, if it's an option??? You could "sign up for one or all local Boxer Rescues, near you are heck a bit further? And you can set the terms and you can tell them a "Pure Bred Boxer" only.
Now if they are half way decedent at there job??? They should know what a "Boxer" looks like?? And if so ... if they happen to get a "PB" Boxer ... rest assure you'd get the first call! Just a thought.
