I've turned many away, but one sticks in my head more than the others. A very nice gentleman came to the house to see the babies and in the two hours he and his adult daughter were there, he asked 17 times how difficult it was to housebreak a yorkie.
After the 5th time, my mind went blank and all I could think of was, what would happen to my babies if they were to pee in his house. I'm sure they were wonderful people, but I couldn't get past that.
I'm never in any hurry to place my pups, they already have a good home with us.
