yay my Ella is due for Rabies in dec.. not a good christmas present for her

.. im going to do the 3 year that way she will be ok for a while as far as that. I dont like vaccines.. but at the same time i take my Ella EVERYWHERE!! She is around many other dogs, which also means she is around there poo and everything else. I keep her up to date on the basics: rabies, distemper, and i think theres one more but i cant think of it at the moment.. but theres been several dogs that have had kennel cough and it just makes me nervous. So i was just doing some research and seeing what u guys think.
Some ppl are not responsible pet owners and u never know what there dog has or when the last time they have been to the vet and since Ella's around so many dogs i feel like i need to be extra cautions.
Im going to be starting another round of agility here in September and were trying a new place bc the last place i went to was more an obedience/ beginners agility class... thats all they offer as far as agility. So i found several places around us who offer intermediate level agility and i really like this one place but they require bordetella.
Thanks for your help!! Your always so helpful!
