Hello,

I currently have a golden retriever and a sussex spaniel.  The golden retriever is perfectly behaved whilst the sussex is not so... He has a very hit and miss temperment.  Sometimes loving people/ dogs and sometimes hating them.  However, he is completely in love with the goldie.  As my goldie is getting older I have to now think about getting another puppy (which i have already thought aboout and my breed of choice would be the goldie again) but i am not sure how he will react to a new puppy. 

Does anyone have any tips on introducing a puppy to the home with a "difficult" dog around?

Thanks!

yes, dont do it!
difficult dog is enough trouble

Yes this would be great if i could however he is so in love with my other dog i know that when he goes he will be extremely stressed on his own :( He really does love company (which he knows)

I was in the exact same position as you two years ago; my boy LOVES dogs but he really has no patience for puppies. He over-stimulates upon first meeting and tends to correct them far more than needed by pinning them down. I found the best way to do it was with Nothing in Life is Free implemented (which it already was), and to make sure that the new puppy was at the core of every good thing. She was on the sofa before him, and he was only allowed on the sofa when she was there to join in. She was fed with him, walked with him, everything (obviously we trained and walked, etc., seperately too) and after about two days there were no more grumbles about guarding toys, me, or food. She can do anything she wants to him and he just adores her; the corrections that still continue with other puppies were never seen with her. She could hang off his beard and bite him hard; nothing. As long as you make sure that YOU control all the good resources and show him that the new puppy is there when they come, as well as extreme supervision, you should be fine.
