I just called the 24 hour vet and they said they could not tell me how much to give her because it was not a med. made for dogs
. I think 1/4 should be fine because she is at least one lb bigger than Juju & Gracie. I am going to try to hold off and not give it to her (this would be the first time for her to have it) but if the itches do not get a little better by bed I may have to.
