I was wondering if anybody have train their cavaliers to use a litterpan while indoor alone (or when it's cold outside or on rainy days) and to go outside the rest of the time. The breeder I will buy my puppy from believe that it would not be a good idea with cavaliers as they are proned to digging (but I would use paper in the pan) and they are maybe too large as a breed for this kind of potty training... What do you think? My husband's parents are owned by yorkshire terrier and they go in litterpan, that's why my husband was interested by this. The first breed we were considering was the papillon and they too can be litterpan train.. what about the cavaliers? are they really too big? did it's impossible for them? did some of you used it or use peepee pad indoor?
