Hi everyone. I haven't posted here in over a year but was wondering could I now ask for some advice? My mum has just 'adopted' 2 two year old cavaliers (brothers) from friends of hers who are emmigrating to Australia. They are absolutely adorable and have lovely little natures and they do get on so well with each other. There is however, one problem....they are not properly housetrained. The family they came from had them in a puppy playpen in their living room and when they werent in this they were outside.I get the impression that they were very busy people, and while they didn't mistreat the dogs, I don't really think they had anytime in their busy lives to properly train the dogs. They are with my mum now and she has them in the playpen and they do not have accidents whilst in it but when she lets them out and around the house they are peeing in the house. I guess I am just looking for any hints/tips/advice. My mum is letting them outside for the toilet regularly and giving the loads of praise and a treat as soon as they go outside. Is it possible to house train two year old dogs or have they passed the age where they can be house broken?
