This is a little off your topic...but I had to share.
I took Syd into PetSmart last weekend to have pictures done...and on our way out we bumped into a lady with a large yorkie. We ohhhhed and awwwed over each others babies for a moment and then I commented on her dog's surprisingly dark fur...since it's not super common to see an adult yorkie stay that black. The poor woman goes "oh no...she's only 2 1/2 months old. I must have looked shocked because she then told me that she is 15.5 lbs...but that the breeder said she shouldn't get any bigger.
Ummmm...I didn't have the heart to tell her that they keep on growing until at least 6 months...and that the chance that her 2.5 month old is full grown is slim to none.
Then she told me that she thinks we must have different breeds of yorkie (what?) since there is such a size difference between our dogs. Somehow I think that she might have over-paid for a mix. I hope she doesn't mind big dogs!
