The drawback to a pack of dogs is the food consumption. In a nuclear apocalypse rationing is going to be difficult already, maintaining stores of kibble or other dogfeed for a whole pack would be a real burden.
If its not nuclear then I guess there’s enough protein to go around.

Id probably try to keep some horses too, if food and drink isn’t a worry. Maybe goats too, but now we’re going into animal husbandry
