Thank you to those who understood that I was just super frustrated and overwhelmed by the demands of this little dog when I posted this weekend. Venting and getting my feelings out did help a lot and allowed me to get back on track. Today marks the second day with no accidents and she even rang the bell to go out to poop!

I think she is starting to assimilate into our household and have caught on to our routine. My golden is still super tired from entertaining the puppy and the puppy is still as barky and energetic as ever. Don't worry- my dog gets a lot of alone time from the puppy each day. But there are times now where she'll just snuggle up to my dog and they'll both take a nap. So cute! They are still sharing and playing well together. We are still trying to get her to stop jumping/pawing at us/my dog when she wants attention. I've noticed small dogs tend to do that when they want your attention.
I will let the parents know when they come back that she had a difficult time for the first week and that she had quite a lot of accidents. Whether it be stress or a need for more potty training they can decide on that themselves. In the end, I really don't know how much training this puppy has had and at this point, it really doesn't matter any more. She now knows sit and lie down. We discovered yesterday that she knows how to roll over! Whenever we ask her to do a command like "paw" she rolls over. Basically if she has no idea what you want, she rolls over lol. And teaching her how to walk well on a leash is a lost cause. It does take time to teach so I'll suggest to the parents that they might want to work on it. She also has separation anxiety which I'm not sure her parents recognize because they did acknowledge that she cries when they leave for work. They can probably work on helping her conqueror that. I don't think I ever said this but her parents are first time dog owners who wanted to get a goldendoodle but ended up with a yorkipoo when they saw her in a pet store. I learned a lot with my first dog and I'm sure they are in the same journey.
While this has been difficult at times, I did learn a lot about little dogs and their needs. It's definitely been interesting but not something I want to repeat. She'll definitely be back for play dates but no more sleepovers for sure. I don't feel that stressed anymore and for that I'm grateful. I can actually sit back and enjoy the company of "my" dogs.
