I live in Florida and have 2 Yorkies and def they are NOT shedding!  I'd be suspicious of food, tap water if on city water, pesticides sprayed in the area...your yard or by govt for mosquito control, etc...detergents, etc., but def something 'general' in nature including pests that all may have encountered.  Your vet may have an idea what the deal is or maybe there are tests, but I would guess that 'ordinary' warm weather shedding is not the reason.  I hope everything goes okay and you are able to get this sorted quickly...worrisome big time.        |
