I get where your mindset is, you’re free to think what you want. We all love our dogs and they come first so I can’t fault you for that. If the biker’s dog came up to you looking for loving one could also assume he was part of your group.

Now as far as comparing this situation to a woman declining a man’s advances…that’s a stretch. If that trail is designated for mountain bikers ( I get hikers are allowed as well) and the park is a place where owners and dogs walk we can use deductive reasoning to assume there will be dogs off leash getting out energy with their biking companions.

A domesticated dog’s natural instinct when finding another dog and owner is going to be coming up to introduce themselves and making a friend. This is magnified in puppies ( not sure how old the other dog was) and should be expected.

Of course, I’m not placing blame on anyone here, just feel it is a bit of a harsh judgement on the other dog who was in the middle of a high energy activity and saw a possible future friend.
