Thanks so much for the information...
I rarely have incidences of marking indoors - I've taken him to several friends' or family member's homes with dogs and I can recall him marking in one friend's house - she has two females, but one is very dominant and I sort of wonder if he was claiming the passive female (his "girlfriend") as his... Not sure though. One house we rented (luckily with tile floors) he marked in when we first moved in but otherwise I don't recall him marking indoors much in the last three years (during which we've lived in now five different homes/places so I figure 1/5 isn't TOO bad...
). He marks a LOT outside though (on 30 minute walks, 20 is spent walking one way along our path, and then coming back along the same route takes 10 minutes
) I know marking outside isn't necessarily harmful behavior, but it can be annoying. At this point, also, I don't think we will neuter him, so I think it might be something to work on. We shall see...
