Please help, my awesome bulldog Mack, 4 yrs old and fixed, "marks" in the house when left alone while me and hubby are at work etc. He goes in phases, sometimes will do daily, or can go days, week with no marking. We recently lost our dog walker who would come mid day ( however it didn't stop him from marking also) I just feel more guilty, we also have a Cavachon- our dog groomer has been helping out- I drop them off on way to work M-W-F and they stay there for the day, on Tu-Thurs she comes by to walk them. Today for example she dropped them off in home at 3pm, hubby got home at 3:15 and he peed near recliner (usual spot) when he does pee, I am sure to scrub area/chair fully using bleach/ vinegar. I have recently resorted to trying "tinkle belts" which groomer forgot to put on him today when brought home. I have been putting them on him Tue/Thurs for past week and he has done well w/out peeing in one until this Tues he had peed in it when groomer got there so she applied a new one when she left and he peed again in the 2nd one. This "marking" has been causing a great deal of friction w/ me and hubby, as Mack was never properly trained when a puppy- husband rescued him from a friend prior to us meeting at approx 8 months of age- I came into his life around 10 months. He has always had behavior of peeing in house but seems worse, more often. I know he hates to be alone (without humans) he never pees at groomers even with all the scents etc. when we walk him outside morning/afternoon he marks all over the place, at least 10 times walking around block. Can anyone provide any suggestions? I also have a crate for him which I tried locking him in, but he will pee in there and lie in it, so now I keep door open and he hasn't peed in it...Sorry so lengthy, wanted to be thorough...Any help would be much appreciated, seen recently at vet, healthy, no urine infection. Thanks!!
