Hello, i hope everyone can provide me some advices. I have a 2 year old dog. Due to the reason that whenever i bring him to the park nearby our house, the stray dogs will always act aggressive and hostile against him, that's why he is very wary around other dogs. I really wish to improve his social skills therefore I'm planning to bring him to a bigger park with more dogs. Can anyone recommend me some methods and precautions to make my dog more comfortable on this matter?
