this is a training issue.  i would ask a trainer for help to ensure you’re doing things right, but i would keep both dogs leashed when they’re together…and crate them when they aren’t, if you live together.

this is just puppy behavior, not aggression…and this doesn’t need discipline, but it sure does need a lot of patience!  your best bet, here?  offer puppy-appropriate toys that can accommodate baby teeth – any petsmart or petco will carry them.  i like plush toys as well as puppy-specific Nylabones and Kongs.  every time he starts chewing on something he shouldn’t, say “no” gently but firmly and give him a chew-appropriate toy.  it’s just that simple!  at this age, too, he shouldn’t be more than a couple of feet from you – shut doors to rooms that aren’t puppy-proofed, and keep clothing and shoes out of his reach.  be consistent, remove bad things from his reach, and eventually he’ll start going for things he knows are “his” without you telling him to do so.

now, every time that puppy nips you, squawk loudly like a puppy would and remove yourself from play.  this might mean you leave the room and shut a door between you and the puppy…and it should just be for a couple of minutes, long enough to get the point across but not long enough to leave puppy unattended.  be consistent.  he’ll figure it out eventually!

good luck!  puppies are a handful.  i don’t envy your position at all. 😉

Just a question. Any idea when the nipping might stop.he will run after my daughter and start nipping at her legs or pants .and whats up with the humping.hes only 3 months.

vet.

any new pet in the household should head to the vet within the first 2-3 days of coming home, anyway.  i’d get your dog in today, if possible…could have giardia or something else going on.

Has your dog recently received Ivermectin or Trifexis?  Both can lead to permanent neurological damage I’m told.  Also some dry dogfood and dog treats are being recalled for fungus contamination.  One dog treat I gave my 3 dogs caused them to have the same symptoms and then they had seizures.  Luckily I figured out what it was and they all recovered.

Dog needs antibiotics and a probiotic won’t hurt either.

males have a penis, females have a vagina.  look on the dog’s belly, you’ll be able to see whether there’s a penis sheath in evidence.  they don’t hide. 🙂

all mammals have nipples. seriously, look for a penis sheath.

actually, because you just got this dog, you should be taking them to the vet (sometime within the first 3 days). ask your vet to help you.

depends on the breed and whether you’re able to keep her away from dogs.

larger breeds mature later, and it’s suggested to wait until AT LEAST their first heat to ensure their bodies develop fully…if not until they are fully grown.  for example, if i were not actively showing my doberman, i would be spaying her around her second birthday in July.

Our guidelines in Col. Potter Cairn Rescue is for females to be spayed at 6 months, same for males to be neutered.  In the past 20 years of owning dogs I have gone from fixing them at 1 year old to this 6 month age recommendation and I see big differences in how my dogs respond.  And I am liking the results of altering them at 6 months.
