we are fostering a mama dog for a local rescue, her pups were 6wks and went to other foster homes. we got her yesterday, and when I picked her up, the lady I got her from said that she had just started scratching at her face more. Perviously she had been biting and chewing on her tail, just down from the base. On the very top of her tail, about 2in from the base there is a 'stripe' where there's little to no hair about 2in long. Since we've gotten her home, she has done a lot of scratching between her eyes and her nose. I mean, like 5+min of straight scratching. She has left her tail alone. Rescue said she had been flea-treated, so it shouldn't be fleas.
Her skin is a little dry, and I'm going to give her a bath today because she's got some puppy stink on her. I'm also going to add 1 (unless I should do 2?) fish oil capsule to her meals in the morning and in the evening to help with the dry skin.
I've got small children in the house, and I'm just a little paranoid about mange. (Too much Animal Planet

)
Is there anything else I can do to help with this itching?
She's also got worms (the kind that look like rice) but she wormed her when I picked her up, and we have the meds to re-dose her in 10 days, so I'm not too worried about that.
