Re: Help me find a good family dog.
My general rule of thumb is when people with small children and babies want a dog, I ask, are you ready for another baby? Some people are taken back by this and confused. If you wouldn't plan another child right now and feel you'd have the time and patience for another child, then you certainly don't have the time and patience for an animal that so many people see as disposable if it "doesn't work out".
A 4yr old and twins... my advice is to wait. Adding a puppy to that is putting a lot on your plate. I know me personally, my youngest is 7 months, and hope my nearly 13 year old dog hangs on for awhile longer because I personally probably would not get another dog until the youngest child is AT LEAST 3 years old.
