There has been some chilling occurrences around the world with dogs being either the victims or the centre of undeserved attention. There is this case in East Africa where dogs were slaughtered and their blood sprinkled on tribal warriors as a prelude to post election violence. There was also a case of a man who was found to have feasted on dog meat in his house. On further investigation and interrogation, it was revealed that the man was a drug abuser, he used to smoke marijuana hence his peculiar aberration. Not to mention the case of a group of girls at the coast who were paid to have sex with male dogs. They were filmed doing the same. Actually, the videos were uploaded on a pornographic website. These incidences show the level of depravity that we humans can sink into given half a chance. There was also a case some years ago where a young man was arrested for having sex with a goat which was found detained in his house. Near our village, there were rumours late in the year 2015 when some thugs stole a goat from the village and raped it before slaughtering it. It seems that there is something terribly wrong with humanity because these examples represent a tip of the iceberg since there is alot of underreporting coupled with the fact that animals don't talk. Matters are not helped either by the authorities who are generally lax when it comes to cases involving animals save for the intrigue, innuendo and drama the cases present in court. The only cases which are pursued with deserted seriousness involve bestiality offences against cows where the owners take labourers to court to answer for the same offences. Needeless to say, the poor animals are taken to the slaughterhouse, a consequence of crimes they didn't commit.
Where are animal rights organizations? Or they only come for photo sessions? I don't know what's wrong with people. How could they sprinkle dog blood, eat his meat or even use animals for sex? Why are humans disrespecting themselves in front of tongueless animals?
The sitting on you thing, well, have you ever seen a litter of puppies interact? They crawl all over each other and sleep in a big pile o' puppies. It's just how dogs are.
Yelping under the bed is likely just attention seeking. It sounds like he gets rewarded just often enough for it to make doing it worthwhile. I bet if you ignored him entirely when he does that for a while, he'd stop.
As to his appetite, some dogs are self regulating with food. They eat enough not to be hungry and stop. (Then you have my dog, who would probably try to eat a 30 lb bag of food in one sitting.) If the dog is healthy, at a good weight, filled with energy, don't worry about it. If this were a new thing, then I'd say go to the vet, because changes in appetite are a huge red flag for illness, but it sounds like he's always been that way. https://www.animalpicturesociety.com/boxer-dog-1877 As for doggie stuff my dog does, whenever we go upstairs (upstairs is carpeted, downstairs is hardwood), Kabota throws himself on the floor and starts worming around and growling and barking. He'll do this for a minute or two, stop abruptly, and walk away like nothing ever happened. No idea. None at all.
