According to the research from Animal people in US and Canada – right from the period September 1882 to 31 December 2012 — Pitbulls and Rottweilers have topped the dangerous dog breeds list because they are supposed to be causing more dog fatalities and injuries.

How To Handle Dog Aggression

6 Tips To Handle A Dog’s Aggression

No one will love to see an aggressive pet in his or her home. Now talking about dogs, it might be jumping and playing around but all of a sudden, it can turn violent. So, how should you control such a dog? Here are few tips listed below to stop its behavior.

1. If you have 2 or more dogs fighting often, separate them

Chances are that you might own 2 or more dogs in your home and they might not get along well with each other. If this is causing aggression problems often – say for example, fighting over food — then think of a wise solution. Feed them in separate rooms. The strategy is very simple here — If you own 2 dogs, who cannot walk together, then have them walked separately.

2. Obedience Training

Your dog’s behavior comes down to the way you have “trained” it. Obedience training is one of the best ways to teach a dog how he or she is supposed to follow certain commands & value your authority.

3. Keep Him Busy

In few cases, a dog becomes aggressive when it doesn’t have anything to do. So, it is important to keep your dog busy with a 20 to 30 minutes outdoor walk, give him few toys or have him play in the backyard with a ball. Whenever they have a lot of energy, feel bored, anxious or lack focus – chances of becoming aggressive is higher.

4. Know Your Dog’s Fear

A dog can really go out of control when it is scared of something. Hence, as a dog owner, you are supposed to know your dog’s fears and take essential steps to make him or her overcome them. And most importantly avoid using negative punishment just to change his behavior. Rather than punishing, try correcting.

5. See A Vet

Even health problems could trigger aggression. Say for instance, if your dog is ill or lacking proper nutrition, then don’t delay in taking him to a vet. Right treatment at the right time is very important. Else, you will face violent behavior from your dog.

6. Get A Professional Help

If everything fails and still you see your dog behaving aggressively often, then get a professional help. A dog trainer, who is well experienced & knowledgeable could handle your dog better. He or she could help your dog overcome behavioral issues, including aggression. Don’t wait until it is too late.

I’ll put aside the poor grammar. There was a LIE told–or maybe it was simply false information and you did not know any better. About Pits, you said that they are SAFE if trained correctly. False, they were bred–by design, to have the killer instinct of ANY terrier with the large jaws of the English bulldog. They are supposed to be aggressive and sometimes even after proper training “something happens” and they hurt or kill a person. NO, it is not JUST bad or missing training. So many people push the line “it’s all how they are treated” and it’s… Read more »

I don’t think the dog you have a picture of , and listed as a pit bull ,is even a pit bull. It looks more like a Rottweiler to me. Look at the faces of the real Rottweilers above . Look at the coloring. Get off here, unless you can provide facts. Nobody coming here is looking for Donald Turnip facts.
