First, a correction: Parker probably didn't weigh 10.9 kg (24 lbs) on Wednesday, because today he only weighed 10.2 kg (22.5 lbs). This is still half a kilo more than last week, and a total gain of 3.5 kg (5.5 lbs) in five weeks, but it does throw off Sean's calculations a trifle.
Second, Parker had some more play time at the dog park this afternoon, even though he met a bully. Parker wasn't hurt, but he could have been. I don't think Cocoa (the gray goofy-looking thing seen here in happier times) has had adequate training or socialization. So when Parker got a little too close to Cocoa's ball, Cocoa had Parker rolling on his back for ten feet before I was able to slap his behind to give Parker a chance to get away. His owner just stood there saying "Cocoa, leave the puppy alone" while Parker was shrieking and desperately trying to get away from his 35 kg (75 lb) assailant. Afterward, while I comforted my shaking puppy and kept a wary eye on Cocoa (who was still off his leash!), I heard her say, "he's usually really good with puppies."
I had a good rant in here, but I've decided to edit it out. Anne said Cocoa and Parker got along just fine Tuesday.
Anyway, Parker shook it off faster than I did, probably because within two minutes of the incident he found a full bowl of dog food in the kitchen. And he did have fun.
