Well, personally for my yearly (Kodee just turned one, so his "yearly" appt will be around 16-17 mos old), I get the exam, and I know he will get his 1st heartworm test. I got him at 7 weeks old, and put him on heartworm preventative right away. He's been on it year-round since I got him. I will get his 1 year shots (just Rabies and the core vaccines, nothing else). I'll ask the vet to double-check his joints (I do this every time we go in for anything
I'm a worried mother!) If he were an indoor/outdoor dog I'd get a fecal test done to check for parasites, but he is a housedog, and is only outdoors on-leash or long-line. He doesn't eat poop or anything "forbidden" because I'm with him. So I'm not worried about worms.
After his one year check-up, I plan on doing vaccines only every 3 years (for all of the core ones and rabies). My vet wants to do yearly til he's 4 or 5, but I don't want him to get that many vaccs. JMO.
Also, once he's older, he may need his teeth cleaned every so often, so that's something that could be done in conjunction w/an annual appointment.
P.S. I forgot - how old is Chance? Is he a puppy or adult? One thing I did with my cat (before I had dogs), was just normal bloodwork once he got to the "geriatric" stage. I will do this w/Kodee once he turns 5 or 6, more than likely. I like to know that the bloodwork looks good once an animal reaches a certain age. You can catch things before they become sympomatic this way. Just my preference - I used to work for a vet, and I've seen so many health problems caught with bloodwork after an animal had symptoms. I'd like to catch stuff as early as possible. I don't mind spending the money for the extra assurance that all is well (kidneys, liver, etc). Just my 2 cents!
