So a few weeks ago we got a companion for our current dog. After these first few weeks I'm wondering on whether we need to rehome our new dog. Our first dog is no longer acting like herself. She used to get her puppy bursts and run zoomies through the yard. Shed get excited when I come home. Shed play with her toys and sleep in my bed. Now she doesnt even want to go into the bedroom. She walks around the house with her head down like shes in trouble. She doesnt get excited about much of anything anymore. She wont play with her toys and she is starting to lose interest in her treats as well. Any advice would be appreciated. I'm not sure what to do. Should i start looking for a new home for the new dog or let this continue on for longer and see what happenes?
