Took Gabreilla to the vets. She has one of those horrible rings on one of her hind legs, it looked as though it was causing her some discomfort and she wasn't putting much pressure on that leg, although she was still running around happily. Was hoping to get it removed, but she needed to be alseep to do it. So will get that removed when she is in for a spay and also get her micro chipped. But she is slightly underweight, what is best thing to do, to put weight on?
