This is just my -- one long-time owner's -- opinion. Other dog people on the forum may have other opinions.
As an owner you're allowed to use some discretion with what you have done. Sure, some things are required or highly recommended.
Rabies vaccinations in Switzerland, I don't think, are a requirement anymore, but rather are optional, depending if/when/how much your dog travels abroad.
Lepto is a vaccination that is only useful if you live in places where it is present. In the US, back in the 80s, DHLPP was a combo shot, but now it's more commonly given as DHPP and the Lepto is optional because Lepto is so rare. I think here in CH they still push the DHLPP though.
Rabies and DH(L)PP come in yearly vaccinations and tri-annual vaccinations. I like the tri-annual, but if you're not staying put and your dog has to travel, it's a waste on the rabies, because you'll still have to have the annual vaccine for many situations, even if the tri-annual is still valid.
Bordatella is always useful , particularly if you have a social dog or frequently board your dog at a kennel. It's also not expensive.
Lyme disease tests are a waste of money unless you're runing around in the forests or your dog is always outside. If you've never pulled a tick off of your dog, Í wouldn't bother with it. This is also a recent advent in veterinary care. I'd only started seeing this test pushed by vets in the past 3 years or so.
Fecal float -- bah. I don't bother with this annually, but I do get it periodically. Again, if it's an indoor dog and they're not out eating shit (and I mean that literally) or garbage, then the odds of getting worms are nil.
Dewormer -- This stuff is poison, and I won't allow it to go into my dog without a reason. So it's gotta be a fecal float first or I have to have seen tapeworms in their stools. I won't allow it "just 'cause".
Heartworm test -- if you're routinely using prevention, then the annual heartworm test is also something that you can have done at discretion. Also, again, use your judgement. What's the risk? were there a lot of mosquitos? do you live near a wetland? Is your dog an indoor dog or an outdoor dog? I get this one infrequently as well.
DENTAL -- don't forget the dental!!! Taking care of Fido's teeth is very important, because he's gotta keep those choppers for 10, 12, 15+ years! Be sure to discuss a professional cleaning with your vet, if one is necessary.
