HI, I'm a stay at home mom and my son is 19 months. I have been doing tons of research on the dog that I want including talking with my vet, talking to training schools and of course the breeder. I understand that it is going to be hard work with or without having a small child. This morning I was talking with a man that put down my choice of dog because he wasn't a purebred and then told me I shouldn't have a dog until my son was 6. I don't want to put the money, time and effort into getting a puppy if I'm doomed straight from the beginning. What do you think, can it be done?
