Thanks for the replies. I will be taking her to the vet, but she was just there for a visit not even a month ago with nothing to report out of the ordinary. The thought of a UTI crossed my mind, but like
Cookiesnmilk said the symptoms don't seem to go together. I feel as though it is probably something similar to what
annah1043 suggested and it's probably something in the yard that she sees and for some reason I haven't noticed yet. (If only they could talk... well the one kind of does already
As far as the invisible fence goes. I realize that this is a hot topic with many dog owners, and I deliberated even bringing it up as I knew I'd get some flak about it.
Rest assured I use this as an auditory reinforcement device not a "Zapping" devise as several suggested. Yorkies are incredibly smart animals, and I personally don't think they need to be "zapped" or shocked to be trained. Habit, routine and repetition are some of the best training methods in my experience. She has not been shocked, nor has another dog entered their yard as I've been out with them every time. They are not ever in the yard without supervision (and I can see the entire yard from where I am, and this is a new place for them so I want to see how they react to their new surroundings). I'm more worried that there is some piece of grass out of place or not to her liking.
I'm also thinking that for some reason she thinks that she's not getting enough attention as of late, and finally that lack of attention has manifested itself into this odd behavior (with the moving and such I have tried to play with the dogs as often as possible, but it's still not the same as before yet).
These three are the first Yorkies of mine, but I've had several other breeds in the past. I didn't know if anyone had similar experiences like this with their Yorkies after a move or some major life change. I know that these things are difficult for nearly all dogs as they need an adjustment period just like we do to get use to their surroundings. I'll continue to increase my time with her as well. The other two love playing, while she more enjoys time sitting on my lap and watching TV or something. So it looks like I'll just have to watch more football.
Thanks again for all the help in this matter.
