Getting a dog in retirement

Hi everyone, wonder if anyone has any thoughts ... I have recently sort-of retired - doing voluntary work and not claiming pension yet. The OH is nearly retirement age. He is wondering how he is going to fill his time when he does take the plunge and I wondered if anyone else has got a dog when they retired. He always had dogs until we married so has experience, albeit not recently. I don't have any experience and I was wary of dogs as a child - not a problem now. We both love walking and being outdoors and have often commented that a dog would be lovely on our walks. Of course, I realise there is a whole lot more to it than that - training etc.... and what about getting a rescue dog. We have a lovely RSPCA centre near us, so could visit and chat to the workers there. Over to Gransnetters - especially anyone who has rehomed a dog when they (the humans, I mean) are 60+ and active. Thanks.
