Ringworm in Dogs Symptoms

In their lives, most of the dogs develop the fungal skin infection commonly called ringworm. Active dogs which spend most of the time outdoors, or even the dogs that are in contact with other pets which have a ringworm, like cats, are most likely to pick up an infection.

In addition to being very uncomfortable and dangerous for dogs, ringworms are also indicated that it can easily transfer to people.

For this particular reason, and for the health of your dog, it is especially very crucial to be vigilant for any symptoms of ringworm in your dog and ensure to seek veterinary attention so as to prevent the condition from spreading.

Step 1: Identifying Ringworm

1.       Watch for itching, irritation, or even nipping at parts of the body.

These are normally the first symptoms of the ringworm in dogs. Above all, these given symptoms certainly give a good indication that you require to inspect the dog closely.

2.       Look closely at your dog’s skin.

If you suspect your dog is having a skin infection, then you start begin by inspecting all its body areas which you suspect that are affected.  Part the dog’s fur so that you are able to see the skin more clearly.

Focus your attention on any the body areas which the dog was itching and on commonly infected regions like the head and forelegs.

To reduce the risk of spreading the infection, you also require to wash your hands after handling an animal which you suspect has ringworm.

3.       Look for bald patches where the hair is shed.

The ringworm in dogs may commonly happen on the head, ears and the forearms.

Are the patches circular? Do they have a bright red rim? If any answer to these questions is yes, then there is a likelihood of the ringworm increasing.

4.       Look for any affected areas for some days.

If you see areas which appear to be infected or even irritated then keep an eye on them. You might be not sure if the ringworm is the culprit immediately, so just continue to observe the situation and then see how the dog’s condition is developing.

It sounds wise to isolate the dog when you have made up your mind. Keep him away from other pets and in one room that has minimal soft furnishings. This allows you to easily vacuum the room and reduce the risk of any contamination.

If it turns out that the pet has ringworm, then restrict its access to any other pets. This will help reduce the spread and risk of infection to others.

Be on lookout for anything that resembles insect bights or even a generalized rash which does not develop on a circular shape. These indicates an alternative diagnosis like an allergic reaction which would need a different course of treatment.

Ringworm infections are normally due to weakened immune systems, while generalized rashes might be brought about in part by over-active immune systems.

Watch the growth of any inflammation.

If the lesions appears bigger and inflamed while maintaining its circular shape, then it is likely that is a ringworm. You will require to get the pet checked by a vet and get an anti-fungal medication so as to treat the condition.

Step 2: Confirming Your Pet Has Ringworm

1.       Take your dog to a vet.

As a general rule, if you suspect ringworm in dogs, take them to the vet so as to get them checked out. Your veterinarian may confirm the presence of ringworm by using several methods and then treat.

2.       Know what your vet is doing when she uses a Wood’s Lamp.

The Wood’s Lamp is a special lamp which is fitted with ultraviolet bulbs and a magnifying lens. The lamp is then switched on and the bulbs are allowed to warm for about 15 minutes.

In a dark room, the animal is carefully examined by shining the Lamp onto the areas and then examining the response through the magnifying lens.

Some species of ringworm in dogs usually glow a fluorescent apple green in presence of the ultraviolet light. If this occurs, then the ringworm is present.

Your veterinarian might then double check her findings by sending a sample to a lab for the species identification.

Be aware that only about 45% of the ringworm species normally fluoresce. So, a negative on the Wood’s Lamp does not imply that the animal is clear. This is a useful way which is used to get a very quick positive, but not any conclusive negative.

3.       The vert might examine the hair follicles under a microscope.

Another way that can be used to get a quick result is for veterinarian to pluck the hairs from the edge of affected area and examine them under a microscope.

Under very high magnification it might be possible so as to see the fungal spores entwined around the hair shaft, which then gives positive confirmation of the ringworm in dogs.

4.       Understand the vet does to a fungal culture if everything else fails.

A fungal culture can give you a definitive response. To do this, the veterinarian might make use of a sterile brush (like a sterilized tooth brush) and rubs it over the affected area.

The head of a brush is pressed against a fungal culture medium, the container is then sealed, and then set aside so as to see if fungus is growing.

Most of the vets might make use of an “in house” test where the fungal culture medium can change color if the fungus grows. This provides a clear indication that worm is present.

It takes an average of about 5 days for the fungus to grow and lead to a color change, although the test is not in any way considered to be negative until about weeks have fully passed with a color change.

5.       Get ringworm treated.

If your dog has ringworm, then your vet will prescribe an anti-fungal medication. While being treated, ensure that you keep your dog isolated, as the infection might still spread to other pets and to humans.

To make sure that your dog does not ingest any given topical medication, ensure you put a wide cone collar (also called the Elizabethan Collar) on it during the treatment.

Step 3: Learning about the Disease

1.       Understand that the ringworm in dogs is a fungal infection.

It is not, an infestation by the worms or even bug larvae. Two species of the fungus are very responsible for the ringworm infection, microsporum and trichophyton species.

This kind of knowledge will assist you to understand both how the disease may spread and how to identify it.

2.       Know what ringworm looks like

As it implies, ringworm normally leaves circular marks or the patches on surface of skin. In early stages of an infection, then there is little that can be seen other than a small patch of hair loss.

This is due to the fact that the fungus grows down the hair shaft, the body rejects that hair as damaged which then falls out. The skin irritation may lead to itching, but even without any evident rubbing the condition may lead to hair loss in the affected region.

3.       Learn how a dog gets ringworm.

One of the primary factors which usually leads to an infection is the immune health of an animal. Ringworm in dogs is common in puppies and even the older animals, though it may also affect animals that have suppressed immune systems.

Dogs that are under stress or even taking some medications may thus be vulnerable. This is due to their immune system keeping the flora and fauna that are normal inhabitants of skin in check. But, if the immune system is not fighting as required, then the fungus might grow unchecked and thus an infection develops.

While the fungi that leads to ringworm in dogs are very common, contact with a heavy concentration of spores may increase the likelihood of an infection. Heavy concentrations are only found on other infected dogs.

If your dog is healthy but still gets a ringworm, it is probably due to being around another animal that had the disease.

Ringworm is infectious and the infected hairs which are shed are a cause of infection in the people or even other dogs. So as to prevent the spread of the disease, sequester all the infected pets and clean up all the fur from the pets before allowing any other pets in the area.
