Here's my new Yorkie (I hope). This is Phoenix we got her Friday and since she's been in our home, she's transiioned to 1 lb, 5 oz bundle of fur, screeching, and diarrhea. We're in love with her but the diarrhea has to stop. Would plain yogurt help? I'm also concerned about her coat. She's 8 weeks and has a thick full coat everywhere but her head and back. Her "beard" is very sparse with black hairs mixed in . She's AKC registered but I'm worried that she may be mixed with another breed (chihuahua perhaps). What do you think? How can I thicken her o=coatl |
