Did you know that dogs cannot bear the smell of pigs?!
The above was found out accidentally by a Texas scientist whilst looking for a way to quieten his Cairn terrier. A spritzer consisting of the smell of a pig was found to completely dumbfound the terrier and stop him from barking, the compound was then tested on groups of dogs and was shown to produce the same effect.
The smell of the (male) pig contains a steroid and pheromone known as androstenone which gets secreted through the pig's saliva and fat.
Apart from having a perplexing effect on the dogs, the compound is proven to be totally harmless to our canine friends.
