Welcome neighbor.

My little guy can't bark! Well, he can bark but only the quietest little squeaks come out!

I took him to the vet and she assured me he has not been "de-bark". Is this common in Yorkies? Believe me, it's nice when they don't bark, my last biewer took a long time to learn to bark. She hardly ever barks and when she does, it's not very loud, this is a good thing, since I have 4 inside dogs.
Vino's coat is very dull and always feels dirty. What kind of shampoo do you recommend? Can little boys wear the cute bows in their hair or is that just for the little girls? I use bio grom. Never any human shampoo. I don't even use baby shampoo, but, bio groom has puppy shampoo(tearless) and if you go on their website, they will send you some free samples. Sure little boys can wear bows, they even make some on ebay with bones, etc. on them for little boys
Potty training isn't going so well!!

Any tips? Lots of praise and consistency. Has he been neutred yet? If not, I would suggest to get him neutred before the peeing turns in to marking.
His little tongue is always sticking out of his mouth (so cute), is that a Yorkie thing? Yes, this is a yorkie thing. You will find a lot of pictures of yorkies on here with their little tongues out.
Alot of the time he will just run in circles around the house, like he is nervous.... normal? Not sure what to tell you on that, mine run, but, not in circles, that you may want to get checked out if it continues
Thanks for reading my thread!
I look forward to getting to know some of you!
ANY advice would be greatly appreciated!!!
