Has she been to the vet since you got her? Some puppies come with fleas and ear mites or can pick them up at your vet's office. Your vet can easily check for them.
The thing to look for is "flea dirt" which is the digested blood excreted by the fleas. It looks like coarse pepper grains. The best place to see it is on her rump near her tail. If you see the specks, try wetting them with a Q-tip. If it is flea dirt, it will turn blood red. |
