Hello everyone! Just coming on here to look for any advice/insight. My parents and I really would like to get another collie, however; we don’t whether a boy or girl puppy would fit our family best? We already have 3 dogs: 1 male rough collie - 7 yrs old and around 90 lbs, 1 male pittie/mastiff mix - 7 years old, and 1 female corgi/pomeranian mix - 5 years old. We have an affinity for boy dogs but are worried that our 2 older males will not like having a uneutered male in the house. Any advice would be greatly appreciated!!!
