i know you may not want to do this with a yorkie (since the have long fluffy hair) but with our labs we would take a clippers and shave a spot on there tummy or backside of 1 of the legs in different spots, or even under there tail, and just redo it when we see that the hair is starting to grow back alittle-we tried collars and polish ect---but they are so full of it as pups and needing a bath almost daily (messy buggers) this was the best way for us not to lose track of whos who, and whos going where. We did it when the forever home ppl came to pick a pup out, that way they were sure it was the puppy they wanted. |
