29/4/18 I have a13 yr old bichon x lhasa dog (who has been done) and 7 month old bichon dog. We cracked the house training eventually..but recently we have major issues with him peeing up furniture, beds, doors in the house. He is a nightmare.. is this scent marking...showing dominance...? Advice please? ..we don' want him done till he us at least a year old.
I would take him to the vet just incase he has UTI or other medical issue, if he is ok then id keep him confined to the room you are in and go back to puppy training basics. Make sure you clean areas where he has been with biological washing powder or similar.
I would reduce his area of activity until the problem was resolved. You could also try rubbing menthol vapour rub onto wooden chair and table legs to make them less attractive. I think the Vicks brand is still on the market.
