They do not look not very well taken care of and need to be seen by a vet. I would think that being a BREEDER you would have an excellent relationship with your vet. With the amount of money it takes to keep a good quality breeding program in tip top shape I am sure that your vet would help in this very serious situation.
I work with a Yorkie Rescue and would be willing to speak to them about helping these 3 if you would be willing to surrend them. Please PM me if you would like to take up my offer.
