Please reconsider the price you are asking....because it sounds like you obviously want to get rid of them pretty badly that you have kicked them out of the house and are keeping them in a barn and/or garage and the fact that they are almost 1 year old and have had little to no training. $1500 is a little much.
There are a lot of people here that have a sincere love, appreciation & respect for the breed & animals in general and put a lot of time into training & caring for them. Please lower the price so that they can find a home quickly where they can be loved & cared for the way they should.
The more you keep them sheltered away and not given daily socialization & attention (frequently), the worse they are going to be & the harder it's going to be for you to place them & find a home for them. Or reach out to a Yorkie rescue for help.
Please understand, I'm not here to bash, just thinking about those poor babies and how they must feel being shunned away...they have feelings too! I am a single mother, have 5 yorkie girls running around spoiled as ever(all have free roam of the house as long as we're home & 2 skin boys, 1 cat & 11 fish and have never had a problem spoiling any of them!
I know it's hard but it can be done! Noone feels slighted in my home!
Best of luck to you!
