I'm looking at getting a second dog and would like to hear your opinions.?

I have a puggle pug/beagle aka mutt also.... We wanted to get him a playmate so we found a corgi at the pound.... We took our puggle to interact with her so wed see how they did together.... I would definantly take urs with u to make sure they get along. Pound dogs are great choices. Sex shouldnt matter just make sure temperants match
