If your going to the dog park have your dog on leash outside the dog park near the fence. This way the pup can be socialized with the other dogs in a safe manner. Do not just bring him in without knowing if he can handle all the other dogs first. It not only could upset your dog but could make the others aggressive also. Also when you bring the dog inside when you feel it is safe then make sure to take him off leash right away. Do not allow your dog to be on leash in an off leash dog park because he can become reactive and the other dogs can become reactive as well.Monday to get here. Husband is going to pick up our new 6 month old lab puppy. Then we are going to the dog park so our other dog and him can meet. Monday can't come soon enough for me.
