Hi! I'm new here and I am going through this right now!! Gypsy Rose is our 3 yr old baby!! She doesn't know she's NOT a baby! We've had Jezebel for 10 days now and Gypsy has done so great, so much better than expected. She was jealous of our 1 yr old grandson! That made us really concerned about this transition. So much so, that we
almost didn't get Jezebel. But we did...lol
Here's what we did... we gave Gypsy lots of attention .. and treats.... the first few days. We would feed her first, let her outside first, offer her a toy first, ect. That way she didn't feel passed over or replaced. We would praise her for being nice to the puppy .... and treats. We also would interfere if play got heated, making ME "the leader of the pack", and telling her to be gentle. I also kept certain routines, such as our special time we always spend together, one on one. It makes a difference to her!
Hope this helps!!
