OMG I LOVE little doxie babies - MY son has 2 boys and they're the cutest things - they are actually like yorkies in many ways and want to be near us all the time -
PLEASE TELL THEM that weiner babies can easily be injured by picking them up wrong - the have very long spinal cords and can be hurt by picking them up that way - I HATE seening someone do that !!!
He is going to need some room to play and leaving him in a crate is just mean - I hope you can show them that you really know what you're talking about and maybe they can learn from you and get that baby an x-pen !
You're a wonderful person to take him for your friend and I wish you the best of luck -
Here is a picture of my son Reid and his baby Briggs taken Thanksgiving ...he's still a puppy and just the CUTEST kisser !
