I'm so sorry you're having this hair loss problem with your babies. I have heard that hypothyroidism can cause hair loss but given that all four of yours are having the same symptoms I strongly doubt that this would be the reason.
I've never heard of yorkies shedding in warm weather but anything is possible. We have four girls and when the weather gets warm here I've never noticed this.
Hopefully someone that lives near Florida will be able to help you out. I guess I'd also speak to my vet to see what they would think of it as well. |
