I have a litter of 7 and have made my picks.
The male I'm keeping has a tail that is as straight as an antenna and at times curls over the back.
He is 12 weeks old and wonder if i should expect this to stay or wait to see if it settles down?

I've seen pups correct the tail carriage as they get older and I've also seen those curl over the back tails stay pretty high. Sometimes it's just a crapshoot!
