I had SIX labrador retrievers (house dogs, of course) at one time in my 40s. It wasn't that I kept going out and adopting them (I did have two that I adopted), but that they just sort of came to me -- one of them I found freezing in the road in southern NM, one of them came to me from a neighbor who had died and left the dog on her own, and one came to me from someone who had adopted her but couldn't keep her, and another was found, injured, by a friend. SO I ended up with six of them. They all got along well and I kept and cared for all of them until they passed. That was a lotta labs in one house, for sure, but I loved every minute of it. My vet's office said I deserved a brass plaque on their counter I was in there so much.
Then I went back to just two dogs, and now I just have one.
