It seems that many Bullies have this problem! It is a good idea to have him checked for a UTI, but usually with that,it would be more than once a day. I would guess that he is upset about something/change in routine,less attention,furniture moved? EBD's are a sensitive lot,and some more tend towards anxiety than others. After checked that urine is clear,you might need to give him more exercise,more attention,or pick up all the "peeables".If that doesn't work,and his health is fine,try all options,and then perhaps the crate! Hope all will turn out okay!
