I googled and saw that Dawn is a dish soap…?

Bunnies should never be bathed thoroughly and if it’s a “bath”, it’s usually just a butt bath to clean a severely soiled bottom. Even then, only warm water is used and if necessary, a tiny bit of natural baby soap. Bunnies are able to clean themselves very well and don’t require baths. I’d think that since dish soap is used to wash away grime, it’d be too harsh on a bunny.

I’ve not encountered fleas on my bunny, but I’ve seen many threads that recommend topical medication like Advantage or Revolution for fleas. Frontline or anything that contains Fipronil should never be used on bunnies.

Do you have a flea comb that you could use to comb her? That should get rid of the existing visible fleas, and the ones that you can’t see (eggs or larvae) can be killed by the meds.

A good point of reference on how to deal with fleas can be found on the HRS website, which is one of the most trustworthy sites on rabbits out there. Here’s an excerpt:

Fleas and Mites

Safe treatments to prevent and kill fleas on rabbits include Advantage (imidocloprid), Program (lufenuron) and Revolution (selamectin). (Note: Advantage has been known, rarely, to irritate the skin of certain rabbits.) The latter is preferred, as it is also effective against various types of mites that cause symptoms of mange, ear canker, and “dandruff” (which is often caused by fur mites in the genus Cheyletiella). Apply to the back of the neck or other area where the bunny can’t readily groom it off. It is essential to thoroughly clean your rabbit’s cage and exercise areas after each treatment to control reinfestation, since fur and dander in the environment may contain mite eggs.

A flea comb is a non-toxic device that takes more patience, but is both physically and psychologically rewarding. Most rabbits learn to love the attention of being flea combed, and it can be used as a supplement to your main flea-control program.

The following products should NOT be used on rabbits:

Frontline (fipronil) has been linked to neurological damage and death in rabbits, although this product is apparently safe for dogs and cats. The manufacturer (Merial) has placed a warning on the Frontline label stating that Frontline should never be used on rabbits.
Flea powders, even those considered safe for cats and kittens or advertised as “rabbit safe”, are not recommended for use on rabbits.
Flea shampoos, even those considered safe for cats and kittens or advertised as “rabbit safe”, are not recommended for use on rabbits. Bathing of rabbits, in general, is strongly discouraged because the stress of the bath itself can cause serious health problems, and has in some cases been linked to the death of the rabbit. Flea baths or dips are NOT recommended for this reason.
For environmental flea control, sprays and “bombs” are not recommended, as they may leave harmful residue that the rabbit can ingest. Safer alternatives include borax and diatomaceous earth, worked into the carpet where fleas leave their eggs.

Baths

Although a rare bunny may grow up swimming in the family pool and going on camping trips where she paddles around in the lake, the vast majority of rabbits, like their ancestors, do not relish getting wet. Even an occasional bath is quite stressful to the average rabbit, and is not recommended.

NEVER–unless your veterinarian advises it to bring down a fever–should you give a sick rabbit a bath. Because seemingly healthy rabbits can have undiagnosed problems, it’s best not to subject them to the stress of a bath. If your rabbit is very badly infested with fleas, there’s a good chance that he is already compromised and may go into shock when bathed. There are many safe alternatives to flea control (see these under “Fleas,” above). Also, a thoroughly wet rabbit takes a very long time to dry, so spot cleaning the dirty area with an application of baby cornstarch (available at any supermarket in the baby section) (do not use talcum, as it is carcinogenic) and then gently combing out the dirt with a fine flea comb is better than a wet bath.
A wet rabbit can quickly become hypothermic. If your rabbit is wet to the skin for any reason, be sure to thoroughly blow dry the bunny until even the undercoat is dry and fluffy. Normal rabbit body temperature ranges from 101oF – 103oF. Because rabbit skin is very delicate, and rabbits are sensitive to heat, never use a blow dryer on a setting higher than “warm,” and constantly monitor the temperature of the air on the bunny’s skin by placing your hand in its path.

There are only a few emergency situations where a bunny should be given a full bath. Unless the fleas are life-threatening, a bath is not necessary. And if it were, I wouldn’t use Dawn soap.

If your bunny simply has fleas, Revolution or Advantage will do the trick. As KurottaBun said, never ever use anything containing fipronil on a bun. Diatomaceous earth is safe for treating bun’s environment. But care should be taken so the powder cannot be directly inhaled by bun. It isn’t toxic, but the fine powder can irritate their sensitive lungs.

It sounds like the vet isn’t very experienced with rabbits. Sometimes what is a completely normal treatment for an animal like a dog or cat is just not at all appropriate for a bunny. Rabbits count as ‘exotic’ pets, so most regular vets don’t have a huge amount of experience in treating them, which can be risky for the bunny.

Dawn soap is extremely stripping and would severely irritate a bun’s very delicate skin – even for just a butt bath.

Sounds like your vet is not bunny savvy. Revolution (or similar) is your best and safest bet.

Yikes, bad vet spotted! Rabbits are indeed considered exotic pets and many vets have no clue about how to treat them properly. Glad that you trust your instincts and are informing yourself! Now to find a knowledgeable vet too.

I think the HRS only lists the clinic itself? It could be that the vet who used to work there no longer does and it’s a new vet who’s not as knowledgeable.
