I hesitate to write about the things my aunt did..
The cheese slid off her cracker a while ago.. but the things she does do, bring out great results.
She had.. well still has, aSpitz
. She bought him as a puppy and waited too long to get him spayed only to watch him mark in her house and outside as well.
The outside marking was not the issue, it was the inside marking ( Of course ) that was not ok.
SHe called Charles ( her son/ my cousin) over for a few days once and they had a discussion about what to do. My cousins idea was the rolled up paper. Charles has always been seen by that dog as sort of an 'alpha'. His behavior is always different with him even though he didnt live in the house with my aunt ( he is 30 )
Knowing this, his idea was to urinate on TOP of the dogs markings and see what happens.
He did it in the yard to test it and sure enough.. the dog would not mark there anymore. He sniffed the area, then went to anotehr popular marking spot and marked there. Apparently, the dog did this in confusion quite a few times. But he did not mark on top of that one spot again.
My aunt had a problem with him digging in her plants. She set aside 1/3 of the yard just for doggie digging, but he would sometimes get carried away and dig more elsewhere.
So, Charles peed all along the border of her plants. For the remaining 2 years she was there, that dog did not dig in her plants anymore.
So, she got the dog fixed, AND had Charles just wipe a little urine on the common marking spots in the house.
He stopped. Period.
Eh.. not my first choice, sort of Hillbilly-ish you ask me, but it worked..
