That makes sense about flight temperature - during certain times of the year, I think it's ok, but not all year round. Especially not in the coming summer months.
I talked with the Chica's owner's sister the other day, and she says that it wasn't Chica that had worms, but another dog, and apparently Chica has all shots required for dogs here on St. Thomas.
I asked if she's ever drawn blood with her biting, and she said no. She bites mostly as a response to play, as she's never been taught not to use her teeth, so when children run and handle her, she's all mouth. I haven't seen her actually be "aggressive," just rougher than most parents would like a dog to be around their kids. The kids were able to pick her up and carry her home after she got loose that day, and really, I get the impression that Chica just wants to be loved. I even played with her for a bit.
She killed an iguana recently. There are other dogs in the neighborhood that she apparently gets along with, but I wouldn't be so sure about cats.
I told the owner's sister about BRAT and about this forum, and she said she'd pass the info on. Hopefully BRAT or we will hear from him soon, and find a good home for Chica.
