I am looking to get a new dog. I have done a lot of research on different breeds but was hoping someone might have first hand advice on my situation. I live in South Carolina and have a horse. We have over 60 acres so there are a lot of trails in the woods and large feilds. I am looking for a dog with the stamina, intelligence and ability to be trained to run with my horse. Most trail riding is done at a trot so great speed is not needed. While I know the sighthounds have the physical ability, I need something that will not run away after game or go sniffing around in the woods spooking the horse. I was thinking about an Italian Spinone, Airedale Terrier or German Pointer. Anyone have experience with a similar situation or know someone who does? Any suggestions on breeds? I also live alone, so a somewhat protective breed would be a plus. Thanks!
