She means that sometimes dogs are better suited outside then in. Our houses are WAY to small to house a great dane.
Same with the shedding and the lack of training.. if you can't deal with a dog shedding, DON'T GET A DOG THAT'S GONNA SHED EVERYWHERE! Simple as that! Don't get it and then justify banishing it to the outdoors... And if you don't have time to train a dog to NOT pee in your house.. then maybe you shouldn't get a dog..
Now I'm sure your dogs are suited for outdoor living.. I'm not saying that your dogs should NOT be outside.. especially if you spend so much time with them out there like you stated... but the REASONS you gave for keeping dogs outside are just plain silly and unjustified! Those are the reasons that so many dogs are banished to chained living outside.. sad and lonely.. those are the reasons we have so many 'problem dogs'.. owners get the dogs and then decide they don't like the size.. the shedding.. or the smell.. or they're too lazy to train it properly.. so out the dog goes! I'm not trying to offend anyone here.. but in NO way are these reasons good ones for keeping a dog outside.. those are reasons to NEVER own a dog.. reasons to get a goldfish instead!
