Hey everyone - new here. I'm planning on getting a new puppy around December. Now, I'm in between a GSD and a Doberman. I have a few questions and I hope for unbiased replies, thanks! It can easily get to -25 Celsius here in my area of Ontario, that's -77 Fahrenheit (I think) and can get up to -30 to -35. In the summer it also get's really hot, around the same temps except above freezing. I know a GSD could handle that cold fairly easily and only need a coat on during the very cold temps, but around what exactly would that be? I know that Doberman's don't have an undercoat and hardly any body fat and everything I've read says they can't stand the cold but here (Animal Planet :: Dog Breed Profile :: Doberman Pinscher) it says they get 3/5 for cold tolerance which is on par with the GSDs (Animal Planet :: Dog Breed Profile :: German Shepherd Dog) I'd like to know at what point does a Dobie need a coat? Their heat tolerance in also on par, and that doesn't seem right either. I'd also like to know at what temps does each breed get to hot. I'm also interested in which breed is more athletic (run speeds, jump distances/heights, agility, etc). I just moved to the country and there are a lot of wild animals around here and a few 'sketchy' people. So, I want a dog that can defend if it is ever needed. Both breeds are obviously great at this but I've read Dobermans tend to be more alert to impending danger, confirm/deny? Intelligence? Stanley Corens research shows GSD at 3rd smartest and Dobermans at 5th, I'd like to hear some personal observations if anybody has experience with both/either breeds. Last of all, I'm not a dog fighter but out of curiosity I'd like to know which breed has a stronger bite per square inch. I watched a video saying the GSD has the second strongest bite next to the Rotty at 238 psi but I've read so many different numbers for both breeds. A strong bite could be good in extreme situations (the wolves and coyotes around here seem to be extremely bold) But, it could also be bad if for whatever reason my dog decided to attack someone/another dog. I'm not saying either of these situations would happen but like I said, it's out of curiosity. I may think of more questions and I know it's a lot of specific questions lol, but thanks for any replies.
