i don't recommend it.
Healthy puppies need no penicillin. If they're sick, the veterinarian will decide which antibiotic to use.
Now why would you want to do that? Does the horse have worms in its system? Check with a veterinarian first to see if your horse does have worms, and if it does, give it dewormer (which is a kind of medicine). Your veterinarian will also tell you which dewormer is safe for pregnant mares and which are not.
Penicillin is a category B medication with respect to pregnancy safety, meaning that it's in the same class as most medications given routinely during pregnancy.
This will depend upon the specific dewormer - some medications are labeled as safe for pregnant horses while others are not. Check the label, and if in doubt, ask your veterinarian.
yes
Penicillin doesn't treat yeast infections, and you want to talk to you vet before giving your dog "human" meds... they have different metabolism than we do, and things that are safe for us are not safe for them.
First, you should stablish a relation by not being on your horse (scrub him, give him food,...) . When you and the horse have a good relation, if you mount him you'll feel safe.
Well If its you, then its your choice, personally I woulden't. Personal Hygene Remember. But if it is the horse, You have to be careful. I once grooomed a horse when it was pregneant and it was fine, but it depends on what the horse is like
Yes, chloroquine is not a related compound of penicillin.
As long as the mother is not allergic to penicillin it should be fine but you should always ask a doctor when a medicine is proscribed to you whether it will have adverse effects on the baby or not. For the source of my answer I've included a link to a yahoo answer where the exact same question was asked.
No
Yes. Horses like apples.
