My 1 year old pyrenees dog went to the dog park a few hours ago. He’s able to get along with kids a people pretty well so we decided to try to get him used to dogs. We made sure to use a leash and walk around to calm him down. Since we went a few hours before sunset, it wasn’t as crowded. A few dog owners were there and we explained to them that we were new and the dog was nervous. They understood. My dog growled and snapped his mouth a few times but didn’t bite. It might’ve been from us pulling him away or it was just a warning. I’m pretty sure and hoping that he didn’t have the intention to actually harm the other dogs, since it happened more then 3 times. No one got hurt and the dogs around who were snarled at were still fine and wanted to play. About half an hour in, He has calmed down. He didn’t snap at anymore nor growled. But he did back away and jump. That’s about it. But suddenly, a dog suddenly charges at us. Like a normal dog, he panicked and snarled at the dog. The owner comes and starts cursing infront of my dad, me, my younger siblings (one was 8). We told them it was our first time and that we were trying to calm the dog down. Ignored. He continued to yell and curse, yelling things like “GET YOUR FUCKING DOG OUT OF THIS PLACE AND DONT FUCKING COME BACK”. And “MY DOG HAS BEEN BIT FUCKING TWO TIMES BY AGGRESSIVE DOGS LIKE YOURS.IF YOU CANT GET THEM UNDER CONTROL, DONT FUCKING BRING THEM”. At this point, my eight year old sister is on the verge of crying cause she was terrified. My dog was normally a calm dog, but was excited. He was already getting used to the park and the dogs before this incident. I’m not really sure if it’s our fault that our dog got aggressive or if it’s his dog for charging at us. Any ideas?
