Health Check make sure you conduct a quick health check on your rabbits each day to ensure your rabbits are fit and healthy... after a while you wont even notice you are doing it. Observe the behaviour of your bun to make sure its normal, Eating and Drinking make sure your rabbit has been eating and drinking, The POOScheck your buns poos to make sure they are normal and not sloppy or discoloured, Eyes, ears, nose make sure your bun's features are free from discharge.
Vaccinations should be given for VHD and Myxomatosis, ask your vet for advice (only use the vhd lapinject brand, as the cylap brand still used by many vets has severe side effects.)
Mite Preventative just as with a dog or cat your rabbit should routinely be treated for mites and fleas, you can buy spot on products in pet shops, or ask you vet to give your bun a dose of ivomec (i treat mine with ivomec every 6 months, a small drop on the back of the neck prevents mites.)
Panacur should be given to your rabbit (9 day course as preventative, 28 days for treatment) every 6 months as a preventative for E.C. a deadly rabbit disease, ask you vet for advice... if your vet has not heard about using panacur to prevent EC... FIND ANOTHER VET!
Coxoid can be used to prevent cococcidosis, treatment is every 6 months, although this is only really neccissary when rabbits are kept in large numbers, or with birds. I no longer routinely treat with coxoid, instead opting for 6 monthly fecal swabs to see if coxi is present... as of yet i'm clear and i will only treat if needed.
