I had two golden retrievers that were abandoned and adopted me. The only thing unusual with having two was they bonded together so tightly I couldn’t take one alone, they always had to be together. If I tried to take one to the vet, the other one would throw themselves at the gate trying to get out. It annoyed the vet the first few times I brought both of them when only one had the appointment, but they learned how tight the two of them were. Also on the downside was when one died the other went within a month.
