Housetrained Dog Doesn't Like the Rain?

Have you tried using disposable "pee-pee pads"? My dog had the same issue, he wouldn't pee or poop outside if it was raining or if it had snowed. Last winter I almost gave him away, I was just so over mopping up dog pee and picking up dog $hit ALL DAY, EVERY DAY for 2 weeks until the snow finally melted! I bought these dog training/house-breaking "pee pee pads" (I think the brand was called Bulls-Eye) that have a pheromone in them that is supposed to attract the dog to it, making them (hopefully) want to do their business on the pad instead of on the carpet or hardwood floor. They were a steal at Kroger - marked down for clearance @ $2.50 for a 30 count bag!!! I bought all six bags left on the shelf lol. I will admit - it took my dog three days to learn to pee ON the pad - instead of AROUND the pad (he's not too bright) but it was worth it.

Now - just in case - I keep two pee-pee pads on the floor where he would usually pee/poop. It is so much easier - and much cleaner - to simply pick up the soiled pad, toss it in the trash outside, and put down a clean pad or two. The pads don't leak, (they didn't for me, anyway) and so your carpet and home won't smell like dog $hit anymore. Just make sure you check the pad often, replacing when needed, and praise/reward the dog when he uses the pad instead of the carpet.
As soon as the ground outside was dry again, I encouraged my dog to do his business outside...so he didn't think that he was supposed to use the training pads 24/7.
Good Luck!!!
