My Mother raised Dogs for over 10 yrs, granted that was over 30 yrs ago now.
She had a very large breeding establishment of over 100 breeding females,
She gave very few needles, Don't ever remember her loosing a dog to any disease.
Granted her kennel was all CKC registered and the place very immaculately clean, well heated with lots of room to romp inside and out, Nothing like these kennels you hear of today, seen a lot of kennels in my time and ain't none came remotely close to my mums setup. It wasn't a kennel, it was a luxury retreat for dogs, you'd have had to see it to believe it.

No outside animal was allowed near any of the dogs and people were not allowed free access within the main kennel either, She had people from all over the world come to buy dogs from her, Some refused to buy a dog unless it came from her, (Sal Pal Kennels).

I have had countless Dogs since then and rarely ever gave any needles to any of my dogs, and all my dogs lived longer then most of its breed, one even lived to the ripe old age of 35 before I had to have her put down.

Granted my two dogs now, Both shi-tzu's have gotten all their needles to date,
Just don't want to take any chances anymore, My Dogs mean the world to me,
However I refuse to feed any store bought dogfood, almost killed my Shi-tzu's,
Never fed dogfood in my life till these two dogs, stupid of me to think I should change now,
Anyways they were lucky and are getting better,

Last dog I had my x shot, when I was not around, (notice how I say X) no warning, nothing just shocked the hell out of me when he so casually said he shot my dog today.
That was 8 yrs ago now, I still dream of my dog and wake up crying every now and again.
I think after experiencing this it has made me more aware of my Dogs and the trust they place in us to keep them safe.

I think getting there shots is a good idea, ask your vet and get what's recommended,
Your dog only has you, Do him proud and keep them safe
