Question:

Is this ringworm? Should I use pet honesty chlorhexidine shampoo to treat it? If so how do I dilute it?

Help, I'm a bit panicked right now. I think my cat, Luna, might have ringworm. I noticed these suspicious round, bald spots on her back, and now I'm freaking out. They’re not red or inflamed, but they do look scaly. I've heard about using Pet Honesty Chlorhexidine Shampoo for cases like this, but I'm unsure if it's the right move or if I should be doing something different. If this is indeed ringworm, how should I be using the shampoo on her? Do I need to dilute it with water, and if so, how much should I be mixing it? I just want to make sure I’m doing the right thing without making things worse for her. Any advice would be really appreciated!

Answer:

Thanks for your question! Ringworm, despite its name, is a fungal infection, not a parasite. It often presents as circular, hairless patches on your pet's skin, sometimes with redness or a scaly appearance. While chlorhexidine shampoo can help manage some skin infections, it’s crucial to ensure that your pet actually has ringworm, as there can be several other causes for similar symptoms, such as allergies or another type of infection.



It's best to get a confirmation of ringworm from a vet because the treatment can differ significantly based on the root cause. If it turns out to be ringworm, your vet might suggest specific antifungal treatments.



For now, if your pet seems uncomfortable, you can keep the affected areas clean and dry and reduce spreading by washing any pet bedding and toys. It's also important to practice good hygiene since ringworm is contagious to humans.



Please note any changes in your pet’s appetite, behavior, or any pus or extensive inflammation, as these could indicate a more serious issue needing immediate attention. I recommend scheduling a video consult with Dial A Vet to get a professional diagnosis and tailored advice for your pet's specific situation.

The advice here doesn't create a veterinarian-client-patient relationship, and our vets can't diagnose or treat your pet remotely. For emergencies or specific medical concerns, always contact your local veterinarian immediately. Your pet's health is unique, and decisions should only be made after consulting with a qualified professional.

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
