We ended up doing the dawn bath. We got most of them off, I think. We are taking her to the vet in the morning. She was apparently the runt, so probably best to get a baseline of where she is health-wise.
Thank you! Maybe about 10-12 weeks? We got her from a friend who rescues animals (mainly horses). She was raised in a barn, and we did see a few fleas. We will give her a bath tonight and I was going to get flea stuff in the morning. Any suggestions on what to get?
