For the last month or so I have had my Mums Rough Collie to stay at my house. He fits in really well and he and Saffy are best friends and we have had no problems at all with him. He does cock his leg and wee up everything in the garden, but I realise that is probably just a male dog thing (Saffy is a bitch).
Yesterday however, we were all in the living room when a dog programme came on TV with a dog madly barking. Both dogs went mad, jumped up barking and looking round. Tyler (Mums dog) realised the noise was coming from the TV, went over, had a good sniff and then cocked his leg up the TV!

I have to say I only found it funny as I have a tiled floor!
Today a relative visited with her little Jack Russel bitch. He was very friendly with her, but then cocked his leg up my door. Is this something he will continue to do does anyone know, or is it because he has only been at my house for a short while?
Thanks,
Fiona
