We are very experienced dog owners, our fifth dog ( a rescue dog) died at a great age two years ago and we are now thinking about another.
4 out ;of the 5 dogs we have owned have been rescue dogs and we have never had any problems with them, even managing to house train a clueless 2 year old dachshund.
I keep looking for a dog that is suitable but most of them seem to have separation anxiety and need someone at home constantly, some are dog aggressive. We have done well with dogs that need trust building up and I thought an ex breeding dog might be a good idea, but all these need an experienced dog to live with. We are semi retired, so DH home 3 weekdays and on the other two I am out part of the day, a suitable dog could come to work with me.
There is a dear little dachshund with problems on Many Tears that I feel sure we could work with but he needs a friendly older dog to show him the ropes.
I'm starting to think I need to buy a puppy to grow up to be the friendly older dog in due course, which sort of defeats the object.
