don't know anything specific about this breed, but I always thought that my Samantha, a Malamute mix, handled the heat okay... Then one year we got a "deep freeze", & the water in the dogs' plastic pool froze solid. I let the dogs out early in the morning, started the coffee, & went to bring them back in... & saw Samantha lying flat on her belly on the ice, smiling. Much as I love her, I don't think I'll ever have another Arctic dog, at least not deliberately, as long as I live in our hot state. but you might go to the Pets Forum on That Home Site! (at the top of this page, there's a thin dark green strip; go to "Forums" & when the drop-down menu appears, click on Home Forums). There are many knowledgeable & helpful animal lovers over there.

SG, Thank you so much for your insight--I believe you are a true "dog whisperer"! Let me clarify a few things and ask specific training & environmental questions: First I'll say, due to you and Annz' kind help, I believe I have corrected one of my problems. When I designed our new home I made space under the wall cabinets in the laundry rm for the dogs' kennels--next to each other. I thgt I was so smart doing this, but for my dogs' personalities, this may be one big problem. So hours ago, I moved Tiger's kennel to a different room (pantry next to L. rm) and he went right in! So now they will have their own space--away from each other. ~~I am also not going to allow either to sit under my desk while I am working--maybe that made Pepper (the Wheaton) think Tiger was getting special treatment (?). #2: The dogs do know I am TOP DOG for I, also, use their food & bowls to show my dominance--pretend to eat a kernel from their bowls before putting bowl down--pick up while they are eating & touch them/their food while they are eating. Never a problem--never a growl or resistance. Also, when we pass thru a door outside I am to go first, after I have them sit-stay & wait for me. I have them sit/lay/stay on command from time to time during the day to reinforce this too. ~~A trainer I consulted after the first attack told me that they both knew I was top dog but I did things to allow Pepper to think she was my equal--that we were BOTH top dogs. So I've been doing these things for a long time---more strictly for about a yr--but now you'll see NOT STRICTLY ENOUGH. ***Let me be specific in my info and question: When I open a door to let them out, Pepper does bolt out the door ahead of me about 1/3 of the time. I use my correction sound (Ehhhhh) and she immediately returns to my side to sit/stay until I give her the "OK" to move. (Sometimes just hearing the correction sound from me, she stops & returns to my side.) Specifically, WHEN I say sit/stay--she ALWAYS obeys. If I give NO command, she will start thru the door. ~~~Writing this out, I see I'm slacking and creating top dog DOUBT in her mind. So she isn't totally convinced that I am top dog? Or am I teaching her that I AM top dog but if she "assumes a top dog behavior" there is no real consequence besides "re-doing the situation" and moving on? SO, I need to go back to square one and take better control--using a lead to control, give commands EVERY TIME AND be persistent. But is it as "simple" as that? I can & will do these things correctly now but what else am I doing or what else can I do. Surely my "allowing" her to even consider disobeying my top-dog status isn't the only reason she's "comfortable" risking punishment in order to attack Tiger? I believe Tiger knows Pepper is Alpha dog and is comfortable with it. It has to be ME & my behavior that affects Peppers attacks. Hope I've been somewhat clear about what I do & don't do in order for you all to help give me instruction & advice. tks again in advance, CB

Please do not leave the dogs alone together. It very likely will end very badly. tiffduke, training will help only to a certain extent. We have been through this. You never know when it will happen - and not just over food. vjtrees - I realize that your posting was from October 2017. I hope for your Dacshund's sake that the Mastiff is now back with your daughter. Please be aware that punctures on the back of the neck need to be checked out by a vet and perhaps meds prescribed to avoid blood poisoning. Dogs, whether they be big or small will go for the back of the neck to ensure that the dog being attacked is trapped. Two of our Dachshund's were attacked in this manner. My heart froze when I saw our big dog holding our Dachshund by the back of the neck and shaking him. There was no reason for it and I should already have left the house - fortunately I had not. The Dachshund was a major Alpha - much to the displeasure of our big dog, who was not alpha. I should point out that our Alpha Dachshund took care of all of his siblings and was not "bossy" with them. Jump forward a few years and we had the same situation - our then Alpha Dachshund was attacked by his Dachshund sibling - who wanted to be an Alpha. They finally seemed to work things out when the little troublemaker attacked our Alpha again. Yet our Alpha did not want to hurt the Alpha-want-to-be. And the attacker knew it. Also, never try to remove the innocent dog without him/her realizing it is you. My husband learned this the hard way - our innocent pup thought he was being attacked attacked on all sides. I hope all is well. We no longer have a Dachshund and I miss them every day.

I am so sorry to read this. Even though you knew it was coming that doesn't lessen the pain and sorrow. I hope you and your family find comfort in remembering all the loving time you shared with Cody.
