Always pick up the older or first dog before the new puppy. Do your best to show the same amount of attention to the first dog as you did before. Let her know that she is still in the #1 spot. Give her a treat or set her food down first. Always greet her first, because she was first. This should help. She is probably trying to let the new dog know that she is first or alpha over him. It does take about a month for them to get use to the new kid on the block.
My two yorkie girls were about the same age difference when I got the 2nd one. Everyone told me not to get 2 females because they would fight or not like each other, but I have never had a problem. They are now 4 and 3 and are the very best of friends. Showing them equal attention and probably the 1st dog a little more or extra is the key. That way they don't feel like their spot is being taken over with you.
Congrats and welcome, I hope this helps. |
