Dog Tip of The Day, April 30

They say dogs don’t feel guilt. I am not sure about this and I have no way to find out. One mistake we make is thinking that dogs have the same feelings, emotions, desires, etc. as humans. This is called anthropomorphism and I have talked about it before. I am sure to some degree they think like us, but I am also sure, it is different in many respects.

Dog Tip of The Day, April 29

I read that an Australian man claimed his rights were violated when a drug sniffing K9 sniffed his crotch. He had been charged with drug possession. The tip of the day for this guy is don’t hide your drugs in your underwear and you don’t have to worry about the dog sniffing your crotch.
