Are Neapolitan Mastiffs good with other dogs?

Yes, some Neapolitan Mastiffs can be good with other dogs, but early socialization around a range of pups is often crucial. Since they are a protective and sometimes territorial breed, it’s really important to help them feel comfortable around other pups both at their home and in neutral, public environments. 

If you’re considering adopting a Neapolitan Mastiff with an unknown history around other dogs, it’s best to do some meet-n-greets with them and a few other pups to assess their compatibility with other dogs prior to the adoption.
