Why is my older dog distant from me and aggressive with new puppy?

Updated On September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Female | spayed | 2 years old | 3.96 lbs

We got our new puppy yesterday! However Molly’s been very distant with me and I’d like to know why? It breaks my heart! Also, her and the new puppy have been play fighting but a little aggressively in my opinion. What can we do to help them get used to one another and to ultimately like eachother? If the new puppy is near Molly will not approach me, what does this mean? Sorry for so many questions

IT can be common that when a new puppy enters the house the older dog might have a change in behavior. Most of the time this is corrected with just time. Molly will get use to the puppy being a around and will start to become more social again. I recommend making sure Molly does have an area she can go with out the puppy to relax and paying her some one on one time to make sure she is getting attention. hope that helps
