Any change in behavior that isn't obvious should result in a visit to the vet if he hasn't been since the behavior started. Tumors can suddenly grow, pain can develop from a sudden condition seemingly overnight so just because your dog has been well a couple of weeks back doesn't mean he's still okay. Pretty much the only way dogs show us they have trouble is by behaving differently due to their discomfort or illness.
If he gets a clean bill of health, it is likely stress-related and not, not disrespect per se. He's just expressing his anxieties and worries. Likely he feels secure and safe in your bed now that the other dog is being more dominant, a role he likely once had. Worried, ill or anxious, frustrated dogs often pee/poo as near their humans' source of highest scent as they can get - their bed or the couch or chair - where they spend much time. Dogs often pee or potty when very anxious or fearful or excited or stressed or even as a sign of deep respect and they chose to relieve themselves closest to your strong scent many times as it is comforting to them. Most sneak around to do it as they know when you see them doing it, you get upset or highly excited so they try not to let you see them doing it. But they are driven to relieve themselves where your comforting scent is. If they have been caught by you a number of times and it wasn't fun, then they sneak into the other room to do it. Some dogs just won't pee/poo in the bed where they sleep or are highly aware of gentle but strong leadership in their humans, will never do it in the bed, no matter how upset they are, so they sneak into another room or another part of the bedroom to do it. But some dogs just will not soil their own bed or that of their master no matter what. Others can't wait to do it for the relief it seems to bring them.
Get that vet check with stool sample, urine and blood tests and go from there.
If nothing is wrong there and there are no obvious signs of pain such as refusing to jump, walk or play rough and her teeth are good with no abscesses or breaks, it's behavioral due to some anxiety or lack of confidence. Start your dog on the Nothing In Life Is Free program to give him some renewed structure and start him on a good obedience training program to get him busy learning, working and gaining confidence, bonding with you and your husband and forming a good team. Then add the other dog into the activities with him as long as they tolerate one another.
Likely what is happening is the new dog is stressing his sense that he was the favored dog of the pack leader, the beta dog, and now is worried about his place in the pack hierarchy so he's relieving that anxiety as best he knows how to do, where he's most comfortable.
The addition and growth and new relationship of the other dog with your husband has changed the pack dynamic, affecting his sense of importance and confidence but he's not disrespecting your husband. He's too busy having his own self-identify crisis. There is trouble in the pack and a dog with a tendency to nerves or lack of self-confidence can get very unsettled during the struggles for hierarchy. Read all you can about pack dynamics and how dogs settle things naturally.
An unsure dog watching all this happen is unsure what to do if no clear leader steps forward to calm things, dispense order and put the members in their place with gentle, loving, patient firmness and give each dog work to do, a roll to play, keep them busy with active, full lives and each dog equally appreciated. Walks outside together could help forget a sense of bonding between the two. Allowing them structured time together in obedience training could help the bonding also.
Until your little guy is more settled and less anxious, restrict his ability to get to your bed or couch or upholstered chairs. Given correct rehabilitation, he could begin to feel more confident and happy within his place in the pack.
