I got Lady first,then Jessie 6 months later and boy did I wonder if we had made a mistake.Jessies arrival threw Lady totally off track,she stopped eating,stopped playing,and most important..turned from being 100% house trained to being a new puppy all over again..we are still re-training her 3 months later.
If I could turn back time I would get 2 pups together

That way,they´d be adapting them selfs to the same new situation together and training them together would just be normal..I think it would be easier...and if theyre brothers,well that would just be perfect
