About 9 months ago I found a stray dog on the street, we took her in and made her a member of the family. I posted about it here http://boards.straightdope.com/sdmb/showthread.php?t=687224
But there hasn’t really been a happy ending for Cricket and us. She been spayed, had her shots and regular vet care. She’s been through obedience training. But she has issues that are just getting worse and I don’t know what to do.
She has always been very dog aggressive. She gets along well with our other mutt (although Cricket is quite dominant), but when she sees another dog she doesn’t know, she just freaks out and acts like she wants to kill the other dog. It makes walks very difficult. And when a strange dog gets loose in the neighborhood (we have wrought iron fences, so she can see out) she goes ballistic. A few weeks ago she managed to bust through the welded iron gate (popped a rivet) and get into a huge fight with another dog. It scares me what might happen.
But even worse, in the last few weeks she has nipped 3 people at our door. Generally when people come to visit, I make her lie down and then once they are in and she sees they are welcome guests, she comes over to say hello. She has always been polite (although occasionally jumpy). But recently she has nipped people on their legs though their pants, and I don’t have any idea why this behavior has just started.
I’m afraid this is going to get worse and she could really hurt someone. She has always been very sweet and gentle to the family, but with the change in her behavior, I don’t know if this could change too.
