If you are giving your dog an NSAID or prednisone and you want to switch to different one, there is a wash-out period of up to 2 weeks to make sure the first drug is gone before the second drug starts.
There is no wash-out period in humans.
Do we care more about our dogs than drug companies care about us?
Probably. Look at mRNA vaccines.
Do humans need a washout period?
I don't know. Do dogs?
It might be that the studies have been done on humans showing that we don't need one, but nobody funded such studies on dogs so for safety they have this washout period that they probably don't need. But I am just speculating.
In the USA, veterinarian offices are one-stop shops for pet care. We wait a few minutes. Then the vet tech sees us. We wait a few more minutes. Then the vet sees us. They do labs, imaging, surgeries, prescriptions, and deliver drugs on the spot. It is a much better experience than most human doctor's offices with referrals, going to separate places for all those things, getting billed seven months later, and so forth. I think one cause is no third-party payer is involved. You either pay the vet for service or you don't. Vets quote prices on the spot. Perhaps another difference is if you don't want to pay too much you euthanize the pet, but I put most weight on the no third-party payer and also licensing requirements separating the various roles. I do not suggest euthanasia for humans so if that ends up making the difference, so be it.
How about in NZ?
Very similar in NZ. Vets are expensive but straightforward.
I think you touched on what feels like an anti-human zeitgeist. People tend to praise the capabilities of machines and animals while disparaging humans. We worry that machines will overtake humans. We protect the eagles, owls, and bears. Meanwhile, humans put too much carbon into the air and must be stopped.
It used to be that people attributed motives to rocks, plants, and animals to explain their behaviors, probably because that's our experience as humans. Then we thought "no, rocks, plants, and animals are more like automata that behave and we humans have higher things such as reason, action, language, exchange, arts, property, cooperation, and capital, or in a word we have 'civilization.'" Now it seems we think "rocks, plants, and animals have consciousness and humans are one among many animals. We only think humans have motives and wills distinct from the others but it's an illusion. Humans are like a virus and must be stopped."
