We recently got a dachshund (31st Jan) she's 5 months old. Since having her my DS whose 4 has been so nasty towards her to the point she is constantly locked in the kitchein for her and DS safety. DS use to be so loving and caring and since getting dpup he has changed. I've tried disaplining DS but nothing seems to be working. Most of the time he's just playing with Dpup but he always goes overboard and ends up hurting her. It's getting so bad Dpup has started jumping up at people's faces and going to bite them and has even bit DS a couple of times. I'm worried as I have a 2 week old DD and concerned that dpup will hurt DD. I don't want to have to rehome dpup and we live my mil who has really bonded with her and gets upset everytime I mention it might be a possibility, but I have tried everything I can think if and nothing is changing. Not sure what i want from posting this really.
