lol....it’s probably pretty funny to watch dogs do it to one another. And if you are around the dog a lot I suppose it wouldn’t be so unnerving. I have a rat terrier, or should I say terror...lol She’s actually pretty well behaved, took a lot of work to get here there. I can see that terriers need a strong personality and a large terrier could really be trouble if not well controlled.
Sometimes it’s hysterical.
Watching a Portuguese Podengo whose butt is maybe 16 inches off the ground *fling* herself upwards and backwards into the air so she can bump the 30” tall butt of the Dobe is pitifully funny.
Bless her annoying little heart, she keeps trying until she scores a good butt bump off of him and then runs away grinning like a fool because it provoked him to finally chase her, what is what she wants above all other things.
The poor Dobe was “raised” by the Podengo and Ibizan Hounds and the latter has a ‘play style’ more akin to Jackals than dogs.
He has adapted to and learned their ‘body language’ and now plays like them, which looks totally goofy.
Back when I’d bring already adult rescue Dobes into the Ibizan infested household, they generally just ignored each other completely..there was an impenetrable language barrier.
The Ibizans would ‘butt bump’ the Dobes in play and the Dobes were like ‘Hey! WTH didja do *that* for?? Idiots!”...;D
[most dogs ‘shoulder bump’, instead]
Odin grew up “bilingual”....:)
