Aside from the usual "be very, very careful because have you seen how badly this has worked out for others in the past" (and sadly quite a few examples here...), the likes of the above is one of the "less risky" approaches; i.e. that it's *his* idea and you push the ball back into his court... he likes the idea of cuckolding, you remind him you'd never sleep with another man (affects your relationship with him, risky for health, reputation, etc.), he's continued to mention that, you ask him if it's just because he wants to see you taken by another male, test his response, wait, wait some more until he brings it up again then make as if you're consider at length preferably while he's horny (encouraged or otherwise) and see if you can work *his* suggestion to *any* other male even teasing by not saying up front what you're thinking so that you can, in effect, let him be the one to suggest the dog (which whom you'll have a good rapport by that time, anyhow), etc.
So that if there's a negative reaction from him it's almost as if he's "to blame" for "pushing" you into the idea (generically) of cuckolding which allows you an easy escape route. And if the negative isn't *hugely* bad give him time to think that over while you're being innocently friendly with the dog IRL day-to-day and let him come back to his cuckolding fantasy again in his own sweet time...
(The best way to get someone to do something is to let them think it was their idea. And you never *need* to tell them otherwise)
And with all the other provisos that you know your husband best after 5 years, etc., and that the canine in question is "on board" with the idea, too.
Oh, and make sure to stress the health benefits of unneutered male dogs which you've been reading up about online to do best by your new family member, if it's required to steer dog selection in that direction. Totally on a scientific basis, of course, but another useful opportunity for test your partner for off-hand comments/responses and get a general feeling for his general disposition.
Remember there's plenty opportunity for "innocent" comments day-to-day; "Come on, big boy...", etc., while your partner is in earshot, many affectionate hip-scratches to doggo and otherwise displaying chemistry innocuously but which could be interpreted otherwise if *he* wished to (and leaving that up to him to do so!). It's surprisingly easy to lay that on thick without anyone jumping to the conclusion of "they must be a dogfucker"...
Best wishes to y'all.
