1. I am not sure what you mean so I'll cover both bases. Those bases are the kids against the pup or the pup against the kids. Pup agaist the kids is pretty explanitory and pose little threat. The other side is yes and no. Yes allow it too be around kids as often as possible. But no b/c kids can be brutal and dogs to hate them. I have always said " Allow kids to come on contact with your pup through adulthood as I don't know of any chioldren robbing and commiting home invasions." That way if your dog gets loose (just a possibility) then a kid hallin a$$ won't cause the dog to go into "hunt" mode as you know dogs are relatives to the wolf and exhibit similar behavial patterns. The only reason I didnt have my last dog around very small kids was that I taught him to be rough. I am 6'3 265 and play hard with my dogs. Then if a younger kid pokes him in the eye or rides a kiddie bike over his tail it wontfase him much.
2.If trained and properly socialized can they still be dog aggresive? Yes. This breed like a few other breeds as you know are more dominant. They will not back down most of the time. If you have them together say when it is 6mo and you have several large cattle bones to give and you hand them out accordingly. Well, one of those days after they are scattered one will decide it want one while another one found a bone somewhere and will go over there to take it. There will be a fight. If it is a smaller dog they will most likely start getting snappy before the other dog has gotten to close and that will trigger trouble for it. This can happen even with a dumb plush toy. I have had one that could tolerate other dogs (females only) and plays rough. The other female doesn't realize or recognize the rough play and starts to get a little ticked off and will growl and bam, another fight. So it is all dependant on the personality of the dog. If it is a same sex combo then you'll have probs most likely. When they menstrate that makes them oftentime very possesive and dominant. But during that time males become receptive and their aggresiveness almost disappears. So it is an even trade. Sometimes a few females and a male may get along but as adults I never leave them alone. It is best to keep them in separate kennels (not the critter kennels either, the 15ft x 6ft. This also means daily activity for each for appx 2hrs. Not the full time but good amount of exercise and then time just to roam around sniff around and do what dogs do. That is why it is best to invest in a female of similar ages as pups but I always prefer the male be younger by say 6mo. Then neuter and spay them. Then less probs. Males will not escape in search of a female in heat that they smell up to 2 miles away. I had a male scale our 6ft fence 2X and that was all it took. The first time I couldn't figure out how he got out and the next day looked and there he went. So major mods were done and adjustments to prevent any escape permanently. I say get the female older as he'll be less inclined to be overly dominant and will have a big sister type of relationship and learn to back down from her when she decides to get "bitchy". With other dogs don't rely on his "niceness" with his mate. I have seen one male I had as being really calm and subtle with her. Well, the neighbors doberman got into the yard and he went and put a world of hurting first before the female got there. When she did arrive he was snapping at her to let him finish up. I had to put some work in to get them settled and apart. I had a long talk with the neighbors as it was there dog who came to my side viahopping the back neighbors fence and squeezing through the neighbor to the right of them which connects to my yard. They had not any pets but a kid that dug holes. Well, there dog worked on that hole and got through. The kid you think as I just said it. Both of the dogs I had at this time were adults. I have had the noeghbor boy(7yrs old) hop the fence to get his ball or whatever. And the way I had raised them, never bothered him ever. Often his mother would freak when she saw them (boy and 2 pits) playing tug of war or ball or just petting them. Never had a prob. I taught them that this kid or others are ok. Now when the meter man came it was a diff story. He was a stranger that was never introduced. But that is how I trained them. Others I have had like the last one could not care less if a total stranger came in and took everything. All he wants to hear is "good boy" and a pat on the side. About the human aggresiveness, these dogs were bred to be human lovers and dog aggresive. I put this out everytime I hear this and get mixed result everyitme. You see other dogs were bred to be man-biters. Pit were not. The real pit. Staffs, bull terriers, etc are not true American Pit Bull Terriers even though from simialr stock at the turn of the 19th century. Anyways, this is for pure example and is not condoned. I in no way shape or form want to go against the animal rights act of 1976. OK, now that that is behind us, here for the example. Lets say you have a pit bull you want to fight. And lets say Tasha does too. You both enter the pit. I guess we need a 3rd person. Ok, lets say I am the referee. If Tasha had a human aggresive dog that might bite you would you want to enter the pit or do you think I would? F no. That is what they believed then and even a few breeders today. They didn't care about a guard dog. In fact any dog that had human aggresiveness was killed as they didn't want the "bad" genes to pass on.
So naturally they are human compadres and aren't really all thast good of guard dogs. Yes, you can train them and make them to whatever you make them. But that can be done with any dog. And some dogs don't have to be trained to be supperb guard dogs. For example, alot of the livestock dogs (shepards included, the Belgian mallinois, the kuvatz, the komondor, etc)...They were bred to protect the herd from other animals and from strange potential threats like strangers. That is why the police ideally pick certain breeds in this catagory.....
Well, I hope this answered your qeustions. As usual I write really long posts. Regardless of what site I am on. (lol) I hear that all to often. If something wasn't clear or you need further in depth answers then just holler at old Snakey and I can possibly tell you from what I know and have experinced. I also suggest a few tools if you plan to keep this dog. Nextly, don't turn your dog into the animal control or whatever based on the fact that your pit attacked the other household dogs. Many state statutes agree that any pit or resemblance thereof, are to be killed immediatly upon arrival, if they make it to the next day. So you got it knowing about dogs already and you just stepped yourself into scortching hot tar or if you play your cards right and liten to old Tahsa and myself then you should be in a cool pool of water in the middle of death valley. Also I suggest you scroll down to to check all the posts I have written as I have had alot of repeat questions......
Enjoy.
