How to stop my pitbull from pulling and yelling at dogs on walks?

Some of this may be curiosity and not knowing manners on how to act around new dogs. Some dogs have a different personality and manners on a leash vs. off a leash. She is young enough that seeking a trainer to help socialize her both on and off leash, in new settings, and around new and familiar animals will help her behavior. The more interactions at a young age, the better as long as they are controlled and the proper behavior rewarded

This may require professional assistance. Have her examined by your veterinarian to rule out medical causes for her behavior. Your veterinarian may dispense medication to help. A certified trainer or veterinary behaviorist should be consulted afterwards to help desensitize or acclimate Misty to other dogs. In severe cases, a combination of medication and behavioral modification is needed to overcome problems.

The answer very much depends on why he's aggressive (fear-based, territorial, play-based, etc) but my general recommendations are to stop ALL punishments, avoid anything that is causing aggression, and never allow him around children. Then you need to find a veterinary behaviorist to work with who can go over a detailed history and diagnosis and treat his issues. If you are unable to find a veterinary behaviorist, your vet may be able to start him on medications and talk about some behavior modification.

Penny is adorable! I suggest getting her into an obedience class or consulting with a trainer. She may be feeling protective of you, which is a good thing, but she needs to learn how and when to be protective. Obedience training is a great first step. Ask your veterinarian if they offer or know of obedience classes, call pet stores like PetsMart or Petco and ask who they recommend.

Please have Lady seen by a vet to help rule out a possible medical cause for her behaviour. If nothing is found to be physically wrong, seek the advice of a dog trainer who uses positive reinforcement techniques, or a veterinary behaviorist, to help curb this behavior. If left untreated, Lady may injure our other dog, a person or another animal. I would advise keeping her on a leash and away from other animals and people until you have the chance to work with a trainer or behaviourist, and keep her in a separate room from your other dog. You may need to muzzle her to prevent injury. Visit the following link for more information on dog behaviour issues. http://www.dacvb.org/resources/for-the-public/ .

Yes, she might be more protecive since her puppy is around. You can try an Adaptil collar and Solliquin chews and see if that helps with any stress/anxiety. You could also take her to a trainer or behaviorist but if she is biting your friends then you may need to confine her when friends come over.

A head harness such as the Gentle Leader or Halti will allow for more control and quicker corrections of negative behaviors. A pheromone product such as the Adaptil collar may decrease any anxiety associated with the move and new environment. If possible, gradually acclimate her to your new neighbors one at a time. Use plenty of praise and rewards as she progresses.
