Idiot dog owner won't restrain dog tells me to leave the park

I love dogs but some of their owners are ******! This video was shot after I spent 2 mins not being able to move because of an aggressive mid-size dog. The dog was not the problem but the owner himself encouraging his dog to go after me. The dog was not big or scary but when i told the dog to get away from me or tried to move away he came in as if to bite and the owner shouted to get the **** away from his dog. The dog was either at my waist or prowling between me and his owner and MY dog which was behind the owner and could not reach. What would YOU do here? Do you love dogs too? How would YOU deal with someone like this! I love dogs. I'm a volunteer at my local humane society and I walk them all week plus rescued one myself. I was about to exercise my Australian cattle dog DOMINO in the local dog park (which he loves). All the dogs ran up to say hi and I gave them some love like you do but one dog kept barking aggressively at me and herded me back next to the park table. I tried every friendly gesture I know but the dog kept pushing me back on the table. The dog owner did nothing all this time telling me he was barking at my backpack, which he was not as you can see here. I politely asked him to calm his dog down or maybe leash him but he refused and I tried to tell him it was bad to let a dog bark at someone in a public place when OFF his leash. He cussed at me , called me a weirdo and told me to leave the park. I could not get my dog as the idiot's friends were petting him and keeping him from coming back to me. Eventually another lady entered the park and I got my dog and left asap. Situation was crazy cos of that man! HE could have defused the situation easily by calling his dog back but encouraged his dog to keep on barking aggressively at me. #bulldog #bulldogsofinstagram #bulldogfrances #bulldogs #bulldoglove #bulldoglife #bulldogpuppy #bulldogsofig #bulldogram #bulldogingles #bulldoglovers #bulldogdays #bulldogfrancese #bulldogmoments #bulldogge #doglovers #doggy #dogsofinsta #dogsofig #doggo #doglove #dogsitting #dogslife #dogsofinstaworld #doggie #dogscorner #dogphotography #dogofinstagram #dogmom #dogsofinstgram #dogmodel #dogwalk #dogood #doge #dogtraining
