5 month old Great Dane puppy

I'm looking to rehome my 5-month-old Great Dane puppy, who is potty trained and up to date on all vaccinations. She'll bring some food and her favorite toys. I’m rehoming her due to the fact that I am unable to care for her. She is very sweet and gets along well with children and other dogs. She is also a little shy, which is typical of the breed.
A rehoming fee of $800 is requested.
Please, only serious inquiries.
