Love the photo of the "flowers". I was so surprised to see what looked like my dog - the dark one. We have an almost one year old mix that looks just like your dog with the dark strip down his back. We had Moose's DNA tested to see what he was, as he was an abandoned puppy when we found him. He is weimaeaner, bull terrier, then boxer, airedale terrier and lab. What a wonderful dog he is and can see your dogs are well loved also! Also a side note the lady who commented before me uses the screen name of one of our cats ... how odd is that????
Have a great day!
