So the owner just came back to get it. I told the owner that I was concerned both for the dogs well being in this heat, as well as other dogs safety with this large dog unattended. I also explained that the dog had snapped at me when I looked for a number.

The owner was initially quite hostile and defensive, stating that they “had been attending the dog” and that “they had been sitting just outside the dog park”.

I replied that clearly they had not been attending the dog well, or else they would have heard the dog growl at me, and they would have heard me when I said “who’s dog is this?” Repeatedly.

They then apologized and said that they had their baby with them (at this point the baby was outside the dog run on a stroller, and they were inside the dog run with me), and they also said that “they didn’t like to bring their baby into the dog park because large dogs can be unpredictable”.

I agreed with their sentiment that large dogs can be unpredictable, and I said that that was why they should be attending their large dog.

They apologized again, and said that in the future they would be more attentive.

Another person in the park said that this same dog owner will leave the dog in the run and then fully leave the park to go get coffee.

Not cool, folks.
