When dogs get older, it is sometimes difficult for them to control their bladder. Take your older Pug dog outside more often during the day. Never punish your Pug if he has an accident in the house.
He is probably already distressed about it.
There are many reasons that your dog may be experiencing incontinence.
Your Pug dog maybe having accidents due to medical problems. He could have a disorder that increases her frequency of elimination. These include cognitive dysfunction, neuromuscular conditions, sensory decline, or brain tumors. Getting help for medical issues early can extend the lifespan of Pugs.
Older dogs have difficulty with change. If there’s a change in the household or her schedule, she may begin having accidents inside.
If your Pug dog only has accidents when you’re gone, it could be a result of separation anxiety.
Have your vet rule out medical problems. If your Pug has no separation anxiety, he may need medication to reduce his incontinence.
Then start house training again as if he were a Pug puppy. Supervise him closely and confine him in a crate. Be sure that confining him in a crate is not causing anxiety. If so, you may have to forgo the crate and keep a close eye on him.
Keeping a watch on him probably won’t be as difficult now as he is not a Pug puppy.
Be certain to give your senior Pug dog lots of trips outside. If you need to be away from home for long periods, consider hiring a dog walker. Train him again using a litter box or potty pads. If you do need to confine him while at work, consider an x-pen with potty pads.
