Hi and welcome! Relate to loving our Yorkie's and the obsession??? Heck yeah!!!
The obsession continues with Yorkie Talk too so take this as a warning...
Hope you love it as most of us do here.
Jojo sounds like a very special Yorkie and is so lucky to have you. I don't have any experience with his special needs so cannot offer any advise...
We love pictures here so would enjoy seeing little pics of your Jojo if you'd like to share and look forward to hearing all about him.
Again, a huge welcome from Schatzie and I.
