It is likely to be very healthy from the pound/rehoming centre - it will have had every check known to man. What is the reasoning for you thinking it would be unhealthy? (thin skin ointment available on request if that is also considered rude)
I agree with Bella, rehome the DH. Or as I do wait until DH is in the USA working (about 40% of the time) and have it ensconsed by his return .

So please don't rule out an adult rescue dog, but do look long and hard at how much time and effort you are able to put in.
Out of genuine interest, are you saying that an adult dog is harder to train than a pup or was the training comment directed at whatever aged dog OP gets?
To explain (before I go bankrupt sending out ointment ) I have only ever rehomed 2 adult dogs and they were easy (an ex racing greyhound, docile as a lamb but anxious and ate the inside of nmy car whilst I was paying for petrol, and an Afghan who was failry sane for an affie).
We are considering a dog next year (not had one since before DD was born) am really torn re the adult/pup dilemma. Obviously all dogs are different, but interested in your opinion.
