Hi everyone, Lately my 4 year old lab has been marking and peeing indoors, usually he is really good so don't know why he's doing it. Anyone had the same problem?
Might be good to have a vet check him out. It’s always a good first step with any sudden change in behaviour. Maybe write down all the symptoms (frequency, any consistent triggering events, behaviour in general, how much he’s drinking) and then go through them with the Vet.
I suddenly thought 'maybe' he has an urinary tract infection, enlarged prostate, stones in the bladder? I think a trip to the vet as @Oberon suggests.
