This is dog cruelty
I was looking to buy a dog like this but when i read about the problems they have I think it is very cruel to breed them. I had a shih tzu that weighed about 15lbs. I loved him dearly. He lived 18yrs.
People do really cruel things to animals just to make a little money and I think it is terrible. I did not realize that these dogs could have problems because they are so small.
