I ask this because my husband is training a dog and it started shaking its head today when it barks. He JUST went to the vet a few days ago and they said NO MITES. He swears my chickens gave it mites, along with my cats being the only way apparently his COON HUNTING dogs can get worms. My chickens show NO signs of mites. I check them twice a week or so and I have never seen a flea, tick or even a tiny mite on a single one of them. This dog has been diagnosed with some sort of blood parasite from a Louisiana tick and allergies (not from our place, he already had them). He is off his allergy medication but still on medicine for the tick stuff and I figured that is the cause of the head shaking. Anyway, what mites and worms do chickens get that they can transfer to a dog.
