We do not have hedgehogs here ( who really are very noisy , no wonder dogs discover them so easily ) but we do have porcupines ....- mine never had an encounter with one ,I only get to see their tracks and start " praying " right away that they are safely up some bushes/hidden away from my girls ;those pics of dogs with well over 100 hundred quills in their heads and mouths circulate regularly - we once got one in at the SPCA , poor Akbash , head all swollen and quills everywhere - luckily all was well soon after they'd been removed , no lasting damage , none in the eyes .
My girls run out regularly at night to keep the yard free of , well , racoons , bear , beaver , whatever ...- for many years , when I still had my Picardy Sheepdog Polka , we had some territorial issues between her and the big beaver who resides in the lake - almost every night in summer she would swim by , smashing her tail loudly onto the watersurface announcing her arrival , which sent poor Polka into a frency ; the end , regularly , her swimming in circles with the beaver - both swimming towards each other , the beaver diving right underneath her after having splashe her with water it was sooo sweet to watch . One of Polka's best dasy was , when we dicovered a dead beaver on the beach , not " hers " mind you , but just as god - as this happened the week before her death , I was extra happy for Polka and let her have as much a go at it as she wanted .....Polka's beaver took over 1 year after Polka's death to return , now young Hermione barks at her , but does not swim after her .
