We have a reasonably well trained 17 month old bitch and we collect a male puppy in 4 weeks time.
I'm worried that all the hard work we've put into training her will go out off the window not to mention how am i going to train the new one.Has any one any tips that might be helpful.We've had two dogs before but there was a 7 year gap and they were both bitches we've never had a dog before!
