I think the monkey on the dogs back is really cute and I know it is not easy to take shots of moving animals, but the back of the dog looks better focused to me than the front of the dog. I think it might have been better if the focus was slightly more toward the front to get the dogs head in better focus.

Hi, I had the focus on the monkey as I didn't want him blurred at all. Could have used a different dof and shutter speed...ahh well.

Prince Edward County....my province, Ontario. Ahhh. There is a lot to love with this post. The look on the dog's face which you rendered nice and sharp oozes with emotion and speaks to us...that dog is looking out for you even whilst frolicking. I like your shutter speed, you caught this , not only on a nice angle which adds to the excitement of the photograph but also you froze the action clearly. The face of the dog is sharp and that is critical. Your exposure is very nicely handled as well with no blow outs or block ups on the fur. You have also composed it well giving Cassie room to run into. Well done.
