Funnily enough my friend has two Yorkies, the little female is a snappy little thing and the male barks, growls and jumps up. Because of the size of them its ok, but I got a nip from the female and it hurt but I didn't do anything about it.
Having a dog is a huge commitment, I got my girl as a companion, just so happened she took to flyball and agility. I enjoyed it but I was breaking as I was running a home, working full time and looking after a dog and horse, it became too much and with her ending up dog aggressive it became too much.
Now we have lots of walks, kisses and cuddles and outdoors things to do at the stables and summer is brilliant we stay out until 9pm.
I have however decided she wil be my last dog, I lost Jaffa my cat 18 months ago and he was just divine, I miss him so much but never replaced its impossible. My horse, he will be the last too
