He's still growing. Like a little god damned weed, he's still growing. I'd put him at close to 16 pounds now. While promising, his sister is now closer to 25 pounds and every bit as big as their mother. It's really something. I'm hoping that he'll get to be that size. I have no reason to believe he won't. He's succeeds at everything he tries to do. This will be no different.
The cat still doesn't like him. It doesn't help that he's 2x the cat's size and 1.5x the cat's weight. He's also getting faster and stronger. That cat's only real defense now is going onto his back, allowing him to use the claws on his hind legs. The dog has started to learn that this is where playtime gets dangerous. When the cat goes onto his back, the dog normally turns around and stands still until the cat gets to his feet. It's pretty funny to watch...a cat, pissed as can be, and a dog standing two inches away facing the complete opposite direction. I suppose it works well for him.
One item that the dog is disobedient with is the cat's food. While the dog is on a "eat when you want" schedule (he's fed 3x a day, but he's fed way more than he needs and it's left out all day), the cat is on a very strict diet (3x a day, but quite a bit less). Of these 3 meals for the cat, #1 and #3 are canned food which, from what I can tell, is delicious. The dog agrees that it is delicious and loves sneaking to the bowl, bullying the cat away, and then eating the food (which takes no more than 5 seconds for him to do).
On the flipside, the cat is constantly sneaking up on Bo's food bowl. This doesn't bother the dog in the least. He's more than happy to share. This goes against the cat's diet, though, so he is normally denied with kicks from me.
In this picture, the cat is sneaking up to the dog's food bowl (which has to be kept in the living room to ensure that A.) If the dog is eating, he's eating his own food and B.) the cat can be kept at bay by my kicks). This is the only reason the cat is being calm with the dog this close. Also, this picture was taken a week or so ago. The dog is a bit larger than this now.
Another piece of not-so-desirable behavior from the dog is his humping. Though, to his credit, he is very precise with it. He religiously restricts his humping to 3 items: other dogs, new people, and his bed.
His humping of other dogs normally comes when he's playing with his sister. He's a sick fuck like that. This is rare, though, as they're normally too busy tackling one another for him to have time to actually hump.
His humping of new people, on the other hand, is not rare. In fact, it's almost a certainty that, if you visit the house (his territory) and he doesn't recognize you, you will be humped. Especially if you are female. While he normally does a quick leg hump or a hover-over-the-shoe-while-slightly-making-a-humping-motion hump for dudes, he generally doesn't leave females alone until scolded. Atta boy. This behavior melts away entirely for those who he is familiar with, though, and I don't recall him ever humping Rachel or I.
His bed humping is my favorite. In fact, it's so much more than just humping. It's pure domination. The vet claims that his gentle humping of strangers is his way of telling them that this is his house and he is the boss. If that's the case, he fucking owns that bed. Though he has slightly grown out of it, there was about a 3 week period where he would daily (sometimes twice a day) engage is a full on raping of his bed. The ritual always begins with him tearing the inner pillow from the outer holding thing. This is done forcefully while he growls. He then continues by holding the pillow in his mouth, shaking it forcefully and growling very loudly. He does this in an open area while dancing around...which is key, because if he hit his head on a corner during a shake, he would most certainly die. Once he's finished here, he engages the bed with his genitals. Sometimes he simply stands above the slain foe doing a hump motion (a good 8" away from making contact), and sometimes he'll bear down on that motherfucker. After he's finished here, he'll begin an indefinite cycle of violent domination, followed by sexual domination, followed by violent domination...over and over again. Each iteration is slightly less energetic than the previous until he ends up passing out on his victim.
Here is a small clip of the sexual domination
His other activity that I thoroughly enjoy is his zooming. Normally paired with a cat battle, he'll oftentimes randomly start running in giant circles through the house. He starts in the living room and either simply does circles around the couch or, more often, laps around the 4-room area that join to make the common area of the house. During the laps, the cat stands alert on the back of the couch and paws violently at the dog as he passes. The dog isn't phased, though. The look on his face is pure determination as he completes lap after lap. Generally 10-15 laps is his limit before his zooming ends at the water bowl.
