The dog park contains way too many unknowns to be certain your dog will have a safe, confidence-building experience there. Do NOT take your puppy to the dog park. It is far more likely that they will become overwhelmed or have a bad experience than gain the proper socialization you are hoping for. Getting crashed into by other dogs can affect their comfort around other dogs for life. If you have a dog that is worried or reactive toward other dogs, do NOT take them to the dog park. This is like being afraid of the water and being dumped into the ocean to sink or swim. The goal is to seek out situations where calm dogs hang out together and go sniffing together. Crashing around, wrestling and mock fighting, or chase, tackle and pin games can teach poor social skills, not good ones. If your party animal loses his mind when he sees other dogs, STOP going to the dog park or day care. For many dogs, the repeated free exposure to other dogs makes them worse. Injuries can also occur, as serious injuries - even death - can result from the injuries inflicted to a small dog by a larger dog. Dog fights also can arise between dogs of any size, so owners must always be watchful of their pet to make sure that safe play is taking place. Viruses can live in the soil for a very long time, and a dog park is a breeding ground for any number of viruses and parasites that can be spread via the soil, water and air. Parasites can be picked up through contact with feces and by drinking water from puddles in common areas where fecal matter has been.
