Once the adoption is complete there is ongoing support. I maintain a private facebook group of people who have Oops puppies. Its a great way to keep up with littermates, habits and any genetic information. It's a super supportive group and we never get tired of puppy pics!
You're free to post there as often as you like. You're able to ask questions, seek opinions or stay in touch. Participation is on your terms. You can lurk if that's what you prefer!
I'm available by email as well. It's not over when you leave the driveway!
If in the event of a life altering challenge and you can no longer keep the pup, they are welcome back here! (and that takes us full circle into the "Why are shelters so fussy")
Feel free to email me with any questions or things you feel I should add to this! firstname.lastname@example.org
