I, too, think your pup is trying to get the other dogs to play. Have you a dog park around your area? Or maybe someone with fun loving doggies, your dog could play with from time to time?

I used to tell Prue "no barks" and I noticed as she got older, she learned to not bark if I told her to keep quiet. It doesn't always work, but she is better. Some dogs just like to bark!

I would work on it, but not worry about it. Puppies often outgrown lots of puppy habits as they get older. Yea!

More pictures please.
