Puppy - Shepherd/Retriever Mix (Davenport, FL)

We are re-homing an 8 week old male, White Shepherd/Golden Retriever mix.
He needs a yard and a caregiver who can give him the attention and exercise he requires.
He's been very sweet and he's very smart, but he's been biting quite a bit, probably due to boredom and not having enough space to get out all his excess energy.
He has been to the Vet for his first check up and is very healthy, and he is up to date on deworming and vaccinations.
Asking $300 rehoming fee.
