English bulldog from hell - can anyone relate ? Rough dog ? What did you do

Has anyone’s bulldog or dog regressed and started marking in the house?

I’m seriously at my end. Without a huge long story, he’s given us SO many problems. It took 2 years to potty train him and we stuck it through. Thousands of dollars in paper towels, thousands in replacing carpets, cleaning pee off the floors 5 times a day, etc. we were told some take longer to get it and to be patient, well he finally got it 2 years later with the exception to a random accident here and there which is no problem for us.

He will now be 5 in 4 months and now is starting to pee on the walls in our house. Does not have to pee, not full blown urine, MARKS.

He pees on the concrete in the patio and we literally have to push him into the grass (he has days where he HATES the grass) apart from other behavioral issues (periodic snapping, excessive barking, etc) I just don’t know what to do anymore. It honestly isn’t a training issue. He was trained and is trained. He’s an asshole point blank. He will go months to a year without snapping then all of a sudden becomes grumpy if bothered at all. Same thing with his other behavioral issues. We tried getting a trainer to come to the house but they just aren’t consistent enough to change. His whole personality is literally the issue.

Now with the marking again I’m just at my last straw. At this point he’s going to live his life in the crate which is not a life to live. He starts to wander while we’re hanging out in the living room and starts smelling and we already know he’s going to mark so we distract the best we can and he’ll just keep going back so we put him away. Today I had to use the bathroom came back and he peed on the wall. He is neutered. We do have another male dog but he has been with us for 2 years and the peeing wasn’t an issue until now.

Any advice will help. I refuse to be someone who re homes a dog but I literally do not know what to do anymore. He is going to trash my house. He also aggressively barked at our friends baby and I’m pregnant (8 weeks pregnant for the third time, 2 miscarriages at 12 weeks and he did not pee out of spite with the other two so nothing to do with me being pregnant) so seeing him get like that raised huge red flags even though part of me hopes it would be different since baby would be here from day 1 and there would be an adjustment period not just - bam, a baby crawling - but taking into account his previous snapping issues, I know I just can’t trust him.

Just so many issues and I really WANT to stick it out for the rest of his life as he’s almost 5 but I’m afraid these issues will get even worse and then rehoming an old dog not only will be harder to find a rescue to take but I feel is just not right. Has anyone gone through this? I feel like a failure. Or maybe he’s just that bad. We have zero issues with our other dog
