Dylan learnt to cock his leg a couple pf weekends ago. The following weekend he marked in my friends house twice. She has a female dog. He was told off straight away. This week he marked 3 times in my kitchen. I didn't see him do it so I didn't tell him off.
I made him a belly band and plan to treat him when he goes outside just like house training, is this a good plan? He doesn't want to go on command now, he always used to.
Any tips would be welcome as I'm very disappointed! I house trained so quickly with no slip ups for months, now this.
