Hi caffi....yes, I think I've seen you on some of the Boards...if not this one. I'm Laura and I'm the furmom to a 13YO dalmatian, Samantha and 3YO lab/mix, Cleo.
When I found Cleo at the Humane Society I was told that she was found as a stray. After having her home for a while I realized that she was very timid with strangers - there is no way that she would have allowed anyone to coax her into a car. In addition, her nipples were very distended. I believe that she had puppies, and then her "owners" decided they no longer wanted her, so they brought her to the Humane Society and said they found her.
Bless you for taking in Maple and giving her a wonderful forever home. She is so lucky to have found you....who knows what the poor little thing went through before you adopted her. And finding sores on her body....poor thing!!
Having a shih tzu is like having any small dog...and it sounds as if you're doing very well in the pet department. What you do have to remember is that she'll need some time to adjust; but since you've already had rescues you know that.
If you want some help with that particular breed you may want to visit over on Popular Dog Breeds - they have a small dog folder. And you can also visit on Dogs and Puppies. Or just ask your questions here....we'll be happy to help in any way we can.
Good luck...and please be sure to keep us updated.
