My husband and myself are looking for a new addition. We have recently lost our beloved English mastiff, and are looking for a new family member. We live in central Louisiana, and live in a camper (30ft x 15) we have 11 1/2 acres of land, and have a chihuahua and cat living with us. We have narrowed it down to 4 breeds, the weimaraner, the German Shepherd, the Swiss mountain dog, and a springer spaniel. Anyone with first hand knowledge of these dogs please give me you opinion on them as a pet please.
