I suggest that they also state ways to prevent your dog from becoming pregnant, like not letting her out unsupervised when she is in heat, etc. I want people to do what is best for their dogs, but I also don't want them to add to the shelter problem. With vaccines,everything but the rabies, I can understand, since your dog doesn't need bordetallo if he/she is not going to be living in a kennel environment or exposed to too many new dogs.
I agree sort of.. maybe they should add information on ways to prevent unwanted/planned pregnancies. But that's also a no brainer (that not watching your intact bitches around intact males, keeping the bitch confined, etc. could lead to pregnancy) to most people and I can understand them not putting it in there as that isn't the reason for it in the first place. To those that DON'T care about their dogs, or the populations, they can easily find another excuse as to why not to s/n their dogs. And as SuZQuzie said, "Would an irresponsible owner really be researching obscure articles on how to prolong their dog's life in the first place?"
It's all about common sense, and unfortunately some people don't have it or care. But it shouldn't prevent the media from posting new findings.
(and btw, my dogs are on the road frequently at shows, they are around many new dogs, go to different places all the time, etc. and still do not get anything besides rabies after their 1yr booster. . . so I don't even give mine bordetella)
