Use can use Advantage or Revolution. I use Revolution. Never ever Frontline though.

See if your cousin can properly dose it for you. As far as I know it only helps with fleas. Revolution helps with fleas and mites.

Ringworm requires a totally different medication.

Obviously if you feel it’s something like fleas or mites, you will want to have the vet check.

I would NOT dust the perma-guard (diatomaceous earth) ON the bunny!!! Rabbits have sensitive lungs/respiratory tracts to begin with and I’d be very hesitant to increase the dust in their environment, especially with something risky like DE, since it’s a lot easier for their tiny, low-to-the-ground bodies to breathe it in relative to dogs and cats. Also, the “pet” formulation of Perma-Guard contains pyrethrin insecticides, according to the label online… while OK in low doses, I’d be really hesitant to use it around rabbits, especially with that risk of breathing it in.

Stick with the pharmaceutical solution- Advantage (imidacloprid) and Revolution (selamectin) are OK, but you definitely want to check with a vet about the dosage. When using these products you also DON’T have to treat the environment unless the infestation is especially severe- the stuff on the animal kills all life stages and breaks the life cycle, so they will steadily die off in the environment without a usable host (humans are not hosts thankfully, but all dogs/cats/bunnies/things with fur in the house need a topical treatment to fully break the cycle) That’s why they’re the greatest thing since sliced bread

Pictures of mites etc. may or may not help, as you need a microscope to see a lot of skin bugs. I would have a vet take a peek at it one way or another, just to choose the right product for treatment and to get the right dosage. Hair loss can be due to scratching from fleas but there are many other things that can cause that as well.

For the Advantage to be effective you need to dose the correct amount- check with your vet or your cousin for the correct dose.  Revolution and Advantage (MUST be Advantage- not Advantix, etc) are safe for bunnies.  But since you bathed the bunny you will have to wait a couple of days in order to apply the topical flea product- since it uses the oil in the skin and haircoat to disperse over the body.

I would check into your flea treatment for the house to make sure it is safe for bunnies- many flea products are toxic to rabbits.

I can see why your bunny might be mad if you sprayed him with essential oils- they are strongly scented and could be irritating to the bunny’s skin or eyes and there is no way for the bunny to get away from it if it is coating the fur- and the bunny will most likely end up ingesting some when grooming. 

Usually its the kitten dosage you’d use on a bunny, full cat size is often too much. And plain water baths still take off too much of the natural oils… it really is best to wait the couple of days.

Just make sure that you mention that you already did a dose and how much – it may not matter but better to let the vet know.\

It took a few doses of Revolution to get rid of the fleas on Pepe.

Just be careful with dosing as most of the dosing and testing is done on dogs and cats- not rabbits.  I know that using it on a rabbit Is off lablel use for Revolution and I think for Advantage too.  That means it is effective but has not gone thru the rigorous testing to get the label claim that it is safe for bunnies.

You should try to reduce the flea population in the environment by washing all the blankets, etc that they come into contact with and vacuuming the whole house- especially where the bunnies like to hide- including under furniture, etc and then taking the bag or canister off the vacuum and dumping it out and getting it into a trash can away from your house- so the flea eggs don’t hatch out and get back into the enviroment.  It will take a few months of treatment to completely eliminate fleas from the environment due to the life cycle of the flea and the different stages it goes thru between egg and adult.

I would mention to your vet when you applies Advantage, how much and that one bunny was bathed before hand.

It is kinda odd that your vet is not at all helpful with coming up with an effective treatment plan.  Just make sure that you are using Advantage and it is purchased from a reliable source (there are counterfeits on the market that could be toxic).
