Advice: Understanding Dog Behavior

[Jay]

It the chocolate one tries to hug you again, a firm "NO! Down." then pet him when he puts his fornt feet back on the ground should do it.

No giving them food or toys isn't the best idea but I know people will do it if they think the dog needs it and, they like the dog.

Just remember they are just canine friends that might be gone any day. You don't know how old they are and, accidents do happen to dogs too.

Okay, roger that Blue. I'm sure I will stumble into both of them tomorrow.

Another question, I stumble into this one stray dog around my neighborhood from time to time. I'm not exactly sure what breed. He looks like a Labrador Retriever. He was very skinny (I can see bones on his tummy) and kept looking for food. He walked away when he saw me. I assume he was scared.

Is it wise to try to approach him and to feed him? Will he become dependent on me afterward?
