Should I buy a new dog bed for my newly-neutered 6 mth dog to prevent so much future ?

wait till hes fully healed and maby a little bit longer say 2 months...he will eventually grow out of this nuisance problem lol i have never heard that they still hump if they smell something because eventually all the hormones go back to normal and they dont recognize that any more but yea i would wait a couple months and if hes still then take it out or wash it.
