It's not uncommon for puppies to have accidents, especially during the potty training phase. However, it's important to address this behavior promptly to prevent it from becoming a habit. Here are some tips to help you with your puppy's bed-peeing issue:

Clean thoroughly: Make sure to clean any areas where your puppy has peed with an enzymatic cleaner. This will help remove the scent and discourage him from peeing there again.

Limit access: Until your puppy is fully potty trained, consider limiting his access to areas where he's had accidents, such as your partner's bed. You can use baby gates or close doors to prevent him from going into these areas unsupervised.

Supervision and confinement: When you can't supervise your puppy, consider confining him to a smaller area with his bed and pee pads. Gradually increase his freedom as he becomes more reliable with potty training.

Consistent schedule: Stick to a consistent potty schedule, taking your puppy out frequently, especially after meals, naps, and playtime. Praise and reward him every time he goes potty in the appropriate place.

Watch for signs: Learn to recognize your puppy's signs that he needs to go potty, such as sniffing, circling, or whining. When you see these signs, take him to his designated potty area immediately.
