4th of July Pet Safety Tips

For many people, nothing beats lounging in the backyard on the Fourth of July with good friends and family—including furry friends. While it may seem like a great idea to reward your pet with scraps from the grill and bring him along to watch fireworks, in reality some festive foods and activities can be potentially hazardous to him. The ASPCA Animal Poison Control Center offers the following tips:

  • Never leave alcoholic drinks unattended where pets can reach them. Alcoholic beverages have the potential to poison pets. If ingested, the animal could become very intoxicated and weak, severely depressed or could go into a coma. Death from respiratory failure is also a possibility in severe cases.
  • Do not apply any sunscreen or insect repellent product to your pet that is not labeled specifically for use on animals. Ingestion of sunscreen products can result in drooling, vomiting, diarrhea, excessive thirst and lethargy. The misuse of insect repellent that contains DEET can lead to neurological problems.
  • Always keep matches and lighter fluid out of your pets’ reach. Certain types of matches contain chlorates, which could potentially damage blood cells and result in difficulty breathing—or even kidney disease in severe cases. Lighter fluid can be irritating to skin, and if ingested can produce gastrointestinal irritation and central nervous system depression. If lighter fluid is inhaled, aspiration pneumonia and breathing problems could develop.
  • Keep your pets on their normal diet. Any change, even for one meal, can give your pet severe indigestion and diarrhea. This is particularly true for older animals who have more delicate digestive systems and nutritional requirements. And keep in mind that foods such as onions, chocolate, coffee, avocado, grapes, raisins, salt and yeast dough can all be potentially toxic to companion animals. Please visit our People Foods to Avoid Feeding Your Pets page for more information.
  • Do not put glow jewelry on your pets, or allow them to play with it. While the luminescent substance contained in these products is not highly toxic, excessive drooling and gastrointestinal irritation could still result from ingestions, and intestinal blockage could occur from swallowing large pieces of the plastic containers.
  • Keep citronella candles, insect coils and tiki torch oil products out of reach. Ingestion can produce stomach irritation and possibly even central nervous system depression. If inhaled, the oils could cause aspiration pneumonia in pets.
  • Never use fireworks around pets! While exposure to lit fireworks can potentially result in severe burns and/or trauma to the face and paws of curious pets, even unused fireworks can pose a danger. Many types contain potentially toxic substances, including potassium nitrate, arsenic and other heavy metals.
  • Loud, crowded fireworks displays are no fun for pets, who can become frightened or disoriented by the sound. Please resist the urge to take them to Independence Day festivities, and opt instead to keep them safe from the noise in a quiet, sheltered and escape-proof area at home.

Mosquito Bite Hypersensitivity

Mosquito Bite Hypersensitivity

Transmission/cause: Hypersensitivity or allergic reaction to mosquito bites. 

Affected animals: Mosquito bite hypersensitivity is a clinical entity in cats living in or near mosquito-endemic environments. 

Clinical signs: This disease generally presents seasonally with the increased presence of mosquitoes. There is no age or breed predilection, however the majority of affected cats spend are indoor/outdoor cats. Lesions generally occur on non-haired or poorly haired areas such as the bridge of the nose, ear flaps, or pads of the feet. Lesions usually present as small raised nodules (papules), that progress to plaques that often have an erosive or ulcerated, crusted appearance. 

Diagnosis: Diagnosis is most often based on clinical presentation and seasonal occurrence, and resolution with avoidance of mosquitoes, however, biopsy with histopathology is very helpful in eliminating other possible diseases with similar presentations, including autoimmune diseases, other hypersensitivity disorders or even dermatophytosis (ringworm). 

Treatment: The best option for treatment is avoidance and control of mosquitoes. Ideally, the affected cat should be kept indoors. If this is not possible, keeping the cat inside during dawn and dusk helps to decrease exposure. Mosquito repellents can be applied to the most affected and exposed areas, however cats can be very sensitive to the effects of certain repellent ingredients so it is important to ask your veterinarian which ingredients are safe. For cats that are severely affected, systemic or injectable steroids can be effective to control inflammation and resolve skin lesions. 

Prognosis: Good, as this has only seasonal occurrence.

Coronavirus/COVID-19 is a concerning topic for people everywhere, including pet parents. As your partner in caring for the overall health and wellness of your pets, we want to ensure you still have access to pet care   during this time. As a result, our facility remains open at this time to provide safe service to all.

Be assured that we have procedures in place addressing a variety of health and safety issues, and while we have always ensured the highest levels of cleanliness and sanitation, we have recently updated our health and safety guidelines in direct response to the emergence of the Coronavirus (COVID-19). These guidelines are based on guidance from the U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO).

These include updated hygiene practices, as provided by the CDC, that are good to follow in all seasons. Things like frequent and thorough hand washing, good coughing and sneezing  etiquette, and avoiding direct contact with others when you are sick. Our team members are being asked to stay home and take care of themselves if they, or their family members are ill. That's one way we can help minimize the spread of the illness for both pet parents and team members.

Please continue to schedule your appointments, as needed. However, if you are scheduled or need to schedule an appointment with our practice and are presenting symptoms of COVID-19, or are confirmed positive, please contact us so we can provide you options for your pet’s care.

Caring for our team members, our clients, and your pets is the cornerstone of our culture. And at this time, we'll need everyone's help to do that. We hope by working together, we can all do our part to help others to stay safe by using these best practices.

If you have any questions please feel free to call a Dermatology for Animals office or our toll free number 877-604-8366.  Thank you!




Also Known As: walking dandruff, Cheyletiellosis 

Transmission or Cause: Cheyletiellosis is caused by infestation of large mites who live on the surface of the skin. The mites live their entire life cycle (21 days) on the host. They are highly contagious, especially among young animals. Adult female mites are able to live without a host for up to 10 days. 

Affected Animals: Cheyletiellosis affects dogs and cats of any breed as well as rabbits and humans. 

Clinical signs: Animals affected with cheyletiella mites can be extremely itchy or hardly itchy at all. They will often get dry and scaly along their backs which can become more severe and spread to body-wide scaling. As the infection progresses, the itching becomes more severe. Patchy hair loss can occur caused be excessive scratching. Some cats may show few signs other than selfinduced hair loss from chewing and pulling out their fur. In humans, cheyletiella mites cause a red raised rash on the arms, trunk, and buttocks that eventually turns into a yellow-crusted area. Human infections usually resolve in 3 weeks if the host animal is treated. 

Diagnosis: The definitive diagnosis of cheyletiellosis is made by identifying the mites or their eggs. Scales can be collected with clear tape impressions, flea combing, or superficial skin scrapings which is then examined under the microscope. Cheyletiella mites are sometimes impossible to find on cats. If cheyletiellosis is suspected in your pet, treatment may be recommended even if no mites can be found. Prognosis: The prognosis for cheyletiellosis is good and usually resolves with treatment.

Treatment: Treatment of cheyletiellosis involves off label use of an anti-parasitic. 

Prevention: Cheyletiellosis usually does not occur in animals who receive regular flea and tick preventative.

What is Vitiligo?


Transmission or Cause: Vitiligo is a hereditary disorder of skin and/or hair pigment loss, and is caused by immune-mediated destruction of the pigment producing cells in the skin. 

Affected Animals: Although any animal or breed can be affected, vitiligo has an increased incidence in Rottweilers, Doberman pinschers, Belgian Tervurens and Siamese cats. 

Clinical signs: Symptoms usually begin in young adulthood. Patchy areas of pigment loss may involve the skin, hair or both. Most commonly affected areas include lips, nose, eyelids, face and footpads. There is no associated itching, inflammation, rash, skin ulcers, or crusts.

Diagnosis: Careful examination of clinical signs and skin biopsy to rule out other more serious causes of pigment loss such as lupus, uveodermatologic syndrome, or skin cancer are necessary. Skin biopsy shows loss of pigment and pigment-producing skin cells, but minimal to no inflammation or other abnormalities. 

Treatment: There is no effective treatment for vitiligo in companion animals. In humans, treatment options include topical immunosuppressive medications or ultraviolet phototherapy, but therapy often causes only partial improvement. 

Prognosis: Although the prognosis for regaining normal skin pigmentation is poor, in animals vitiligo is only a cosmetic disorder, with no effect on quality of life. In some animals, spontaneous repigmentation may occur.

Discoid Lupus - DLE

Discoid Lupus 

Also Known As: Cutaneous lupus erythematosus 

Transmission or Cause: Discoid lupus erythematosus (DLE) is an autoimmune disease in which the animal’s own antibodies attack normal components of the skin. DLE is a benign variant of systemic lupus and has no systemic involvement. There is strong evidence that sunlight induces and/or exacerbates the disease process. 

Affected Animals: DLE affects dogs and cats, but where it is the second most common autoimmune disease in dogs, it is very rare in cats. There appears to be neither a sex nor age predilection in either species. Collies, German shepherds, Shetland sheepdogs, Siberian huskies, Brittany spaniels, and German shorthaired pointers have demonstrated predilection for DLE. 

Clinical Signs: Clinical signs of canine DLE include loss of pigmentation where the brown/black color of the nose changes to a slate blue or pink color, redness, and scaling of the nose. The disease can ultimately progress to significant destruction of the tissue, resulting in ulceration and crusting of the nose. Lesions may rarely involve the ear flaps, mouth and area surrounding the eyes. The affected dogs are otherwise healthy. In cats, DLE most commonly affects the ear and face, resulting in redness, scaling, crusting, and hair loss. Aside from the dermatologic lesions, affected dogs and cats are otherwise healthy. 

Diagnosis: As this disease can resemble other more serious diseases, including epitheliotropic lymphoma (cutaneous lymphoma), pemphigus, and systemic lupus, it is important to get a definitive diagnosis. Diagnosis is based on a supporting clinical history and biopsy with histopathology. Biopsy of the Discoid Lupus nose requires sedation or general anesthesia. The nose will be numbed prior to biopsy, and sutures (stitches) will be present where the biopsy was taken.

Treatment: Treatment is variable and often dependent on severity of lesions. In some dogs, sun avoidance alone may be sufficient in controlling the disease. In more affected animals, therapy may include any individual or combination of the following: topical and/or oral steroids, oral doxycycline, an antibiotic with anti-inflammatory and immunomodulatory properties combined with niacinamide, a vitamin B derivative, and tacrolimus, an immunosuppressive topical ointment. Sun avoidance is essential in all affected animals, with applications of sunscreen providing additional protection. 

Prognosis: The prognosis of DLE is generally good, as this does not cause systemic illness.
