Hello everyone! I am looking to get some advice on what to do with my older dogs behavior to the puppy I adopted almost two months ago.
I have a 5/6 year old Australian Cattle Dog (ACD) that I adopted 3.5 years ago. She wasn’t well socialized when I adopted her and sadly I didn’t do much to correct that. I know she made friends with other dogs when I boarded her but the lady told me she was awkward and didn’t know what was okay and what wasn’t.
I adopted a 4 month old ACD two months ago. They got into a couple of scuffs the first 24 hours and then a major drag out. All the fights were started by the puppy. They did so well together outside the house, we decided to keep them completely separated except for long walks. After a few weeks we also started crating them side by side.
We reintroduced them inside the house a couple of weeks ago. We started with small periods of time and then slowly increased it. They were doing incredibly well together. Constantly playing, licking each other’s faces. I was so happy and proud of them!
Then two days ago, my older dog attacked the puppy out of nowhere. They were playing and I didn’t see if there was anything to initiate it. We separated them and have kept them apart except for crating and walks. My older dog still seems upset. Growling at the puppy in her crate...today she lunged for her again when she was on the floor with her belly up.
I am absolutely dumbfounded on what happened and what to do about it. They were doing SO well together. We had a solid two weeks with zero incidents. Idk if possibly the puppy has started going through hormonal changes since she is almost 6months old now and my older dog can sense it?
I would greatly appreciate any advice. We have worked really hard to get them to be friends so we can keep the puppy. We aren’t ready to give up on them having a happy functional relationship yet.
