how often to vaccinate

Question
I want some non biased info on how often getting my pets vaccinated.  We have 2 dogs and a cat.  All adult.  One dog about 10 years old and super healthy still acts like a puppy and even recently discovered he could hop my parents 6 foot fence no problems so I took him in our home since our fence it quite higher. We also believe he is wolf hybrid but have given him the yearly shots since we have had him for many years now.  The second dog I believe is britney spaniel mix maybe with some pit or american bull dog and he also very healthy.  Bout 5 or 6 and does get little bit of allergies and scratches his eye and it gets runny once in while.  Tried different dog foods and even medication and benadryl and nothing really changed it so I just let it be.  It doesnt seem to cause him any pain and he doesnt rub it enough to hurt himself.  Other then that he is very healthy and we have had him about 3 years and had his shots done twice I believe.  It has been almost 2 years since his last round and a year for the other dog.  The cat we have had about 2 years and not really sure how old she is.  Maybe 7 or 8 and she is pretty healthy except for what we thought was respitory infection and had her treated and it didn't help so we pretty sure it is asthma.  She will have difficulty breathing a couple times a day and will kind of cower close to the floor and breath heavy for a couple minutes and then she is ok.  It's not from hairballs either because she rarely does that.  But she is a happy cat and seems very content and comfortable.  I feed the cat science diet and I started the dogs on that but switched to nutro lamb and they seem well on that.  That is there backround.  My question is should I get them more vaccinations?  They rarely leave our house and the cat is inside only since she is declawed.  I have read so much info about how often to get them the shots but it's hard to know what to do and even when people say studies have been done, who knows who has financed those studies and lab tests and influenced the results.  I don't want to harm our pets and also would like to save that money if it's uneccessary.  But then on other hand I remember we had to put our black lab down when I was a child from parvo and how horrible that was.  I think he was still a puppy or very young adult and I don't know what vaccinations he had or not but it was a tramatic experience none the less.  Most likely he was up to date on shots because my mother was very responsible and loving with our pets.  What do you suggest?  I am also concerned because a friend that my wife visited last week just told us her dogs have parvo and are going to die and my dogs have not had shots within the last year or two.

Consult with your veterinarian about how often you should vaccinate your pets.  Vaccines play an important role in maintaining the health of our pets; your vet will discuss his/her views about vaccinating with you and together you can determine how often you need to give your pets shots.
