I have been visiting YT for a while now. Google took me here when I was first studying up on Yorkies before we picked up Gracie in April. I later joined as a member, but haven't been very active posting, but I have gotten a lot of very good information on lots of topics, including:
1. Vaccinations. I made sure we did her rabies shot

separate from her other booster.
2. Floppy Ears. One of hers went floppy while she was teething. I taped it off and on for a while and it finally went back up on it's own.

.
3. Diarrhea. She got giardia about 2 weeks after her spay and was on 3 rounds of antibiotics.

The last 2 she was negative for the parasite, but still having loose stools. Thanks to reading YT threads, I started her on yogurt and a probiotic while on Prescription I/D canned food and gradually changed her to a different food (California Natural Lamb & Rice) with a lot fewer ingredients (She had been on Innova puppy but couldn't tolerate it after the giardia). I also sent for some Pet Flora probiotic and it really firmed up her poops quickly.
And this is just a partial list!
So.....thanks thanks thanks to YT. What a great Forum!
