Ringworm in Bulldog

How do you treat ringworm in bulldogs?


Hi Sandra,

Ringworm is a fungus, not a worm, and is characterized by crusty sores
that make a circular pattern. It lives in hair follicles and the skin.
It can cause the hair to fall out around the affected areas of your bulldog.

Often it is spread by contact with cats, who seem prone to carry this fungus.
It can also be carried by rodents and even found in the soil in some areas.

The only sure way to know your dog has ringworm and not some other
parasite or fungus is to have your vet do a skin scraping and grow a
culture from it.

It can be treated with topical creams like miconazole (Tinactin) or clotrimazole
(Lotrimin) that you can purchase without a prescription. If it’s really
bad, it may need oral antifungals or a different medication prescribed
by your vet.

Be aware that it is contagious and can spread from your dog to you or
members if your family. It is not highly contagious, but be careful not
to touch the affected areas of your dog.

If your bulldog does have ringworm you and your family members
should wash your hands after contact with your dog.

This fungus thrives in dark areas like the hair of your dog. So when
your dog sheds it can leave the fungus around your house. It would
be a good idea to vacuum daily and change the vacuum bag every day.

You can also clean counters with a 1:10 dilution of bleach and water.
Sunlight is also a good killer of this fungus, so put dog beds and
even your dog out in the sunlight.

Here’s a detailed description and history of ringworm:

Your Bulldog Pal,
————-follow up question——–

My vet suggested a medicated dip for six weeks to treat this  fungus. Is that good for a bulldog?

Also, I can’t find Pinnacle dog food in the upstate of SC. Can I purchase it on line?


Hi Sandra,

Does he have a particularly bad case with sores all over his body?
If so, the dip may be the best way to go.  It is made of lime and
sulpher.  It will keep the fungus from shedding into your environment.

I’d prefer topical treatment if it’s a mild case.  You could try

* Clotrimazole (Lotrimin, Mycelex)
* Miconazole (Micatin)
* Terbinafine (Lamisil)

any of which can be purchased over the counter.

There are also oral treatments if he has it all over his body.

Oddly enough ringworm usually goes away on it’s own after about 4
months.  And some dogs fight it off better than others, depending
on the strength of their immune systems.

I always try to treat with the least amount of ‘invasion’ to my dog,
so I’d try the topical first.

My bulldog Vivy got ringworm when she was a puppy.  She had little sores
all over her body and was treated with the oral medication Fulvicin.
Vivy had been ill and we were concerned that she might not be able to
overcome it without meds. The puppy that brought it into the
house got over it on his own.  None of us got it.

So it’s a tricky question as to what to do.   It depends on what you
are comfortable with.

Here’s another site with information on ringworm:

As for the Pinnacle, it’s made by Breeder’s Choice and is available
online.  You can shop online or search for a retailer on their site:

Good luck and let me know what you decide to do and how it
works out.

Your Bulldog Pal,

    Great information….My nephew is currently dealing with ringworms. I was not sure about animals having ringworms until I completed my report. Thanks for the information.
