Hiya Jane, thanks for replying, We have a male whippet that is 7 years old, (Fenn), a male dachsund that is 3 years old, (Frank), and then our 8 month old male puppy (Webley) another whippet. None are neutered. Webley is house trained when we are at home, there are never any mistakes, we have tried leaving him just with Frank, as he gets on very well with and plays alot with, leaving Fenn in another room when out, but because this hasn't been successful we now leave them all together. Webley doesn't always soil the house, so we think he is improving, then he will, just, to prove us wrong!, He chews bedding, and anything he can reach mostly decorative items. I work for myself so am fortunate that I am always popping home during the day, I am always home lunchtime and sometimes work from home, I can leave him some mornings and he is not too bad then other times I can be gone for just an hour and it is total devistation, I never know what I will come home to. Hope this is of some help, thanks Andrea.
