Dog agressive - then cries?

Question

I took my dog to dog parks ever since puppyhood, she's now almost 6 years old and still acts weird around dogs. First of all, she will most likely attack small dogs for no reason, secondly with big dogs, she'll always run up to them, get all stiff and will growl -ready to fight, if that dog doesn't respond and goes away, she begins to cry. Why do you think that is and how can I help her?

Answer 1

Answer 2

HM that is a difficult one.Have you spoken to your vet about it. Possibly take her to training classes.  

Answer 3

With everything you have said here, your dog does not like other dogs.

Why not respect that and walk her in another place than a dog park.

Or stay home and play ball with her.

Sooner or later she will contact a dog she either harms, or she will be harmed by a bigger dog. Don't take that risk.
