That’s a bit misleading- as soon as the puppies made it into their new bunny hutch home, it began. This week, however, I’m noticing that it’s effective.
I papered one half and put a puppy bed in the other. The first few days, there were accidents, and the bed went thru the wash last night ( thank you downstairs neighbour for letting me wash on your day, I owe you a drink!) to get rid of the residuals, but by and large, the puppies are learning that paper = pee.
Earlier, I set Espresso down on the paper and said “peepee”, and he went. His brother Cappuccino heard peepee, stood up, wiggled his bum and toddled down to the paper to go as well. I’m not sure if it’s coincidence or awesomeness on the part of the puppies but I am all for it!
