Thanks all, he marks incessant when out, literally if its not moving he,ll wee on it, been like that for a while.
When I say I don't make a fuss, I do tell him off, like say NO and pick him up and put him outside and say OUTSIDE just like with a pup.
Its hubby who enhances with the panicky voice which doesn't help I guess.
No its been 6 months since he has had his booster.
Will keep an eye on this over the next little while.
For 2 years he had no accidents in the house then within a few months there is this!
Thanks all.
