I bought 2 dachshund male puppies from the same litter and I need advice on how to separate them. I have noticed that one of the pups (puppy B) is more attached than the other. He can’t do anything with out his brother (puppy H). Puppy B when given alone time he is scared of everything he won’t even let me pick him up or pet him and will cry/ bark/ whine every chance he gets. Puppy H won’t cry and will play somewhat but will only want to be held or receiving affection, he will also not eat unless hand fed directly into his mouth. The most trouble is at bed time/ night time puppy B will cry all night long if his brother puppy H is not in the same crate as him. The potty training has also gotten a bit difficult, when they are separated they will properly use there puppy pads but when they are together they go anywhere in the house and rip up the pads into pieces/ play with them. I have purchased a shock collar but I’m afraid to use it since they are only 3 months old and don’t want to traumatize them but my neighbor has complained about puppy B crying so much that I’ve been caving in and letting them sleep in the same crate even though their crates are right next to each other literally touching. Does anyone have any advice on what I can do?
