"We had three labs. Put them together in a large kennel for the day while we were away. They broke out and killed all our chickens - something none of them would have done alone. My vet laughed at us. Told me three dogs are a pack.What your vet told you is true. When we lived out in the rurals, local farm dogs would get together in the morning and go off on jaunts together. Individually, these dogs were fine, but as a pack, they shagged small cattle, goats and chickens.
Dogs who understand that they are the Omega ina pack of humans are great.
Dogs who think they are teh Alpha are a problem.
A dock pack is a real problem.
A pack of dogs are no longer controlled by humans. Think a bunch of wolves without fear of man.
