Cephalexin: A Safe and Effective Antibiotic for Canine Infections

As a dog owner, it can be incredibly stressful to watch your beloved pet suffer from an infection. Whether it’s a urinary tract infection, a skin infection, or a respiratory infection, you want to do everything you can to help your furry friend feel better. In many cases, antibiotics are the most effective way to treat bacterial infections in dogs, and one of the most commonly prescribed antibiotics is cephalexin.

Cephalexin is a safe and effective antibiotic used for decades to treat a wide range of bacterial infections in both humans and animals. In this article, we’ll examine cephalexin and its use in treating canine infections. We’ll explore when and why cephalexin is prescribed for dogs, how to administer the medication, and what dosage and duration of treatment is typically recommended.

By the end of this article, you’ll better understand cephalexin and whether it’s the right choice for your dog’s bacterial infection. So, let’s get started!

What is Cephalexin and How Does it Work in Dogs?

Cephalexin is an antibiotic that belongs to a class of medications called cephalosporins. It works by interfering with bacterial cell wall synthesis, preventing the bacteria from building and repairing their cell walls and ultimately leading to their death.

In dogs, cephalexin is primarily used to treat bacterial infections, including urinary tract infections, skin infections, respiratory infections, and other soft tissue infections. According to a study published in the Journal of the American Animal Hospital Association, urinary tract infections are one of the most common infections treated with cephalexin in dogs, accounting for approximately 14% of all bacterial infections seen in dogs.

Cephalexin is an effective medication for treating bacterial infections in dogs because it is able to penetrate bacterial cell walls and reach the site of infection. Once it reaches the site of infection, it disrupts bacterial cell wall synthesis, preventing the bacteria from growing and multiplying. This allows the dog’s immune system to fight off the infection, leading to a faster recovery.

Dosage and Duration of Cephalexin Treatment for Dogs

The type and severity of the infection, the dog’s weight, and their general health all affect the dosage and duration of Cephalexin for dogs. Specific instructions on how and for how long to administer the medication will be given by your veterinarian.

Cephalexin is often given orally every 8 to 12 hours to dogs at a dose of 10-15 milligrams per pound of body weight. Depending on the nature and severity of the infection, the course of treatment can last anywhere between 7 and 14 days.

When giving your dog cephalexin, it’s crucial to carefully follow your veterinarian’s instructions because either an overdose or an underdose can have negative effects. Do not take two doses at once if you miss one; instead, just carry on with your regular dosage plan.

Your veterinarian may also recommend blood work or other diagnostic tests before and after treatment with cephalexin to ensure that the medication is working as intended and that your dog’s infection has been fully treated.

Precautions and Contraindications for Cephalexin Use in Dogs

While cephalexin is generally safe for use in dogs, there are certain precautions and contraindications to keep in mind. Some studies have found that cephalexin is associated with a higher risk of adverse reactions, such as gastrointestinal upset and skin reactions, in dogs with preexisting liver disease.

In addition, cephalexin may interact with certain medications, such as probenecid, which can increase the concentration of cephalexin in the blood. According to a study published in the Journal of Infection, the co-administration of probenecid with cephalexin in dogs can lead to a significant increase in the concentration of cephalexin in the blood. While this may help expand the clinical benefits of Cephalexin, there is also an increased risk of toxicity.

Furthermore, cephalexin should be used with caution in dogs with a history of allergic reactions to cephalosporin antibiotics, as cross-reactivity may occur.

The Importance of Buying Cephalexin from a Reputable Pharmacy

According to a report by the World Health Organization, 1 in 10 drugs sold worldwide, especially in low and middle-income countries, are counterfeit, and this includes veterinary medications. Counterfeit medications often contain incorrect dosages or ineffective ingredients, which can lead to ineffective treatment or harm to your dog.

Thus it is important to buy cephalexin from a reputable pharmacy to ensure that your dog receives a safe and effective treatment. A reputable pharmacy provides medication that has been manufactured and stored properly, reducing the risk of contamination or ineffective treatment. Moreover, buying cephalexin from a reputable pharmacy ensures that you are getting the right medication prescribed by a licensed veterinarian.

Online pharmacies like PetCareRx offer both prescription and non-prescription medications, as well as nutritional supplements for pets and other pet care products. They have a wide selection of medications available, including antibiotics like cephalexin, and offer great discounts on their products.

In addition to providing high-quality medications, an online pharmacy offers the convenience of home delivery. This can be especially helpful if your dog requires ongoing medication or if you have a busy schedule that makes it difficult to make frequent trips to the veterinarian or pharmacy.


By providing a comprehensive overview of cephalexin and its use in canine medicine, this article aims to help dog owners understand the benefits and potential risks of using this medication to treat their pet‘s infections.
