Hi,
I only have one yorkie, My little Bella the light of my life. I spoil her rotten but if I was to do it all over again I would have 2. They need playmates. Bella is 4 now and had a traumatic experience with a black lab and has issues with other dogs now. I think that they need a friend and I am still looking to add another little girl to my home. I think it would have been easier to start with 2 as all the house training is done at once.
I used to feel the way you do only wanting one to take everywhere with me but that is not always possible. You can't take them into some stores and I know here you can't take them into grocery stores. So a little friend for when she is home is a good thing.
I am on a waiting list with a breeder on N.Yarmouth one of her pups should have a litter this winter. I am very excited about it.
Congratulations on your new little furbaby.
Jay
