Yep that sounds just like Pip, only he can move faster! 
Sounds like a fantastic walk for Maz. I love it when they can just stay off-lead and have a blast doing what they love to do best.
I have had two lovely walks today, as it's ds1's birthday, so dh took the morning off and I was able to walk them separately while he helped ds set up his new Minecraft server.
Hate to admit it, but it's so much easier and more pleasant walking them individually at the moment. Both lapped up the 1:1, both had bang-on recall I had a spare hand! They are now spreadeagled across the living room floor snoring with contentment and stinking of garlic sausage!
Pip hid behind me when an elderly gentleman and his lovely gentle Westie came to say hello. There was this little white ball of fluff, wagging her tail at a pair of eyes and pointy noise just inching themselves round from behind my knees. It was perfect actually, because she just stood there giving off lovely friendly signals, but didn't approach him or do anything pushy. He did come out from behind my legs eventually, but still wasn't sure he wanted to approach her, which seemed mutually acceptable. 
So much calmer and better for him than when I have both dogs and Lurcherboy is desperate to say hello, which ramps up the excitement and puts Pip on edge.
Yesterday we met yet another tiny Cockerpoo puppy, It could only just have been allowed out after injections it was so tiny. I was walking both of mine out of the park on-lead and the owner just let this teeny little bundle of fur career straight up to them like a miniature tazmanian devil. It's a good job neither of mine are aggressive, because it would only have been a mouthful if they were. Lurcherboy said an enthusiastic hello and Pip looked keen but chose not to approach, then pup decided ds1 was the best bet for scamming a treat and chose to climb up him instead. Poor pup, it won't be long till it has a bad experience in that particularly park if it's owners don't stop allowing it to approach every dog it sees. 
Think I might see if I can manage to take Lurcherboy in the morning before dh goes to work and walk Pip separately later, then do a shorter joint one in the afternoon. That way they both get some 1:1 attention and training and hopefully their behaviour when walked together will improve. They're not badly behaved, but they do get over-excited recently, when I walk them together on my own.
We also popped to a local farm-shop cafe early on to buy dh a milkshake and cake. Sun was out and we had the dogs with us, but luckily it's a quiet enough place for us to leave the boot up, with the dogs locked in the crate. They were treated to watching a field full of sheep and lambs, but the daft dogs were more intent on watching me through the cafe window. 
There was another car parked next to us with a Cockerpoo in whose owners had done the same with their dog in a crate and the boot up and were sitting at the next table to ours by the window. Perhaps we'll start a trend.
