He is my youngest son, and even though I promise I did not do any of these things on purpose.... he behaves very much like a dog.
First of all, I think it is important to know that the very first 'word' he ever spoke, at around 9 or 10 months old, was to make the kiss sound, calling for Akira to come to him.
He learned to play fetch early on, and was even ahead of Yukon there for a bit. Yukon has now caught up and surpassed Puppy, especially with speed and style, but Puppy does always 'out' the toy/ball, whereas Yukon really has to think about whether or not he wants to give up that beloved thing in order to continue the game.
Puppy has also learned a few other 'tricks'. He sits pretty when it is training time, and waits for a treat. I use kibble for treats, and (get ready for it) Puppy prefers to get a piece of kibble for his 'sit', rather than the offered cheerio. Gross right? Oh, just wait, it gets grosser.
There have been several times when I have had to pull Puppy away from the toilet, once he was dunking his cookie in there!, *GAG!* It is a really good thing I am not a germa-phobe, but really, so gross.
I have also found him happily gnawing away on the dogs bones, sticks, whatever.
Oh, and he tries to eat out of the garbage can. Seriously, my sister said 'Have you tried telling him that he is n o t a dog?' No, I haven't the heart.
One of Puppy's favorite past times is drinking out of the dog's water dish, on all fours, and eating his cheerios out of the dog's food bowl. I put some cheerios in a tupper-ware for him to snack on, and he promptly dumped them on the floor and started eating them like a dog. When Yukon came and helped him, oh there were tears. So next I put the cheerios in a big flat plastic container (you can see it in the back of the picture) but Puppy just dumped them out of there into Yukon's bowl and started to chow down. Down, on all fours.
