Morning,
I have an 9 month old Tibetan Terrier (not a real terrier) and am thinking about adding another as she turns about 1. I adore TTs and it will probably be another but I was also thinking about wheatons and Airdales.
I can never find any Wheatons for sale so I guess they are pretty rare.
Also, I have never had a terrier however so am inexperienced with them.
My TT is pretty easy going, loves all other dogs and is generally a good pup (apart from all her chewing) nowadays.
We live opposite a big park where she knows many of the dogs and can often go off lead.
My TT is left alone for a few hours without much problem and she's not a barker unless someone is around the property (lets make that the whole close!). I wouldn't want a breed that is prone to barking a lot.
We live fairly rural, decent garden etc. My kids are all teenagers now so no little ones around.
