We have decided on a older dog because they are 'ready made' lol. we would rather take on a dog that has a few years left so they can live out their time in a nice environment, not in kennels.
Having an older dog would be good for Sally, a nice calming influence (she is more relaxed when with other dogs)
Some older dogs get a new lease of life when put with a younger pet (our old girl lady certainly did)
They have some degree of training and socialisation.
As for costs, Sally is only 20 months and costs a fortune!
We want to wait until we are settled in our new place but in a few months we should have a 'second hand' dog to add to our family.
