Great point, yes please check w/ your vet first, as you have to make sure people meds won't interfere with the specific dog (due to age, breed or any other meds the dog may be taking).

I have used these at one point in time or another, for my critters, fosters, transports etc...
I added a few that can be used on ferrets & cats


Sterile eye drops (for minor eye irritations)
peroxide (clean wounds or induce vomiting)
buffered asprin (soreness)
glucosamine, chondroitin &/or MSM (stiffness/joints)
benadryl (allergies or colds mainly for my ferrets though, but have used on dogs)
Pepto-Bismol upset tummies
diaper rash creams (irritated skin, especially urine burns from old or sick animals... also mainly used on my ferrets)
pedialyte or gatorade (dehydration)
neosporin (cuts, wounds just make sure your pet does not lick it off)
selson blue shampoo (dandruff, ring worm, some other skin irritations)
athletes feet meds (ringworm... for me the spray works best)
dromamine (car sickness) can be used for dogs
vaseline (hairball treatments for cats & ferrets)


oh I am sure I have used other items but I just can't remember at this time
