Help with Beagle Pups and suddenly wetting the sofas

Hello Everyone,

I am new to the forum, and had a question. We rescued two four-month-old Beagle sisters 3 1/2 months ago. They have not been the easiest to house train, but we are definitely making progress. All of a sudden, at least one of them has begun peeing on the couch cushions upon which they nap from time to time. I know this is not dominance behavior, as they are quite submissive to everyone. I read a post recently from a dog breeder of 40+ years that between the ages of 7-9 mos., puppies like toddlers begin to sense their own vulnerability and that of their owners, and often pee on spots that smell strongly of their owners, such as couches and beds, as a means of covering the scent against enemies. Has anyone else ever heard this, or know of any other possibilities? Dogs are not supposed to pee where they sleep, so this is terribly perplexing and aggravating, as it will be impossible to keep them off. They are already blocked from going upstairs. Can't keep them penned constantly!

Also, does anyone know how to keep them away from tables where we eat?! They have been scolded many times and know that they aren't supposed to, but do it every chance they get...they chew everything in sight and are always hungry!

Thanks so much,
Carolyn
