Friends came to stay with their lovely little skinny, ugly terrier who they'd said might try & hump our dog but 'it's a dominance thing, it'll pass after a short while'.
This terrier was the randiest, most frustrated little fecker in existence. It abused our spaniel puppy (only 5months old then! Oh and male) for the entire weekend without let up so poor little devil spent entire time racing round house & garden, tail between legs & looking over shoulder in abject terror.
This thing was so randy that because it could never quite catch our dog for long enough, it would jus carry on humping thin air standing there.
Omg so gross watching someone else's dog do humping motions.
Eventually it did get satisfaction, on it's own, all over our kitchen floor. I'm heaving just remembering.
Friends kind of laughed about it 
.
I got the mop out.
That dog is never staying here again, our poor spaniel was so traumatised by the weekend.
Why don't they just chop its balls off? It would be 200% improvement on a dog that literally only does shagging..
