When your dog has a bacterial infection, your vet might prescribe cefuroxime, a second-generation cephalosporin antibiotic used to treat skin, respiratory, and urinary tract infections in animals. Also known as Ceftin, it works by stopping bacteria from building cell walls, which kills them or stops them from spreading. It’s not a first-choice drug for every infection, but it’s often picked when other antibiotics like amoxicillin don’t work—or when the infection is caused by bacteria that resist common drugs.
Dog antibiotics, medications prescribed by veterinarians to treat bacterial infections like cefuroxime must be used carefully. Giving the wrong dose, stopping too early, or using human-grade pills can lead to treatment failure or dangerous side effects. Dogs can react differently than people—some get vomiting, diarrhea, or loss of appetite. Rarely, allergic reactions like swelling or trouble breathing happen. Always follow your vet’s instructions exactly. Never give your dog leftover human antibiotics, even if the name sounds familiar.
Cefuroxime dosage, the amount of medication given per kilogram of body weight, varies by infection type and dog size. Most vets prescribe 7.5 to 15 mg per kg of body weight, given twice a day with food to reduce stomach upset. A 10 kg dog might get 75 to 150 mg total per day, split into two doses. But this isn’t a one-size-fits-all rule. Your vet will consider your dog’s age, kidney function, and the specific infection. A skin infection might need 10 days of treatment, while a urinary tract infection could need 14. Skipping doses or stopping early lets surviving bacteria become resistant—making the next infection harder to treat.
Not every dog needs cefuroxime. Veterinary antibiotics, a broad category of drugs used to fight bacterial infections in animals include amoxicillin-clavulanate, enrofloxacin, and clindamycin—each with different strengths. Amoxicillin is often tried first because it’s cheaper and gentler. If your dog’s infection doesn’t improve, or if lab tests show resistant bacteria, your vet may switch to cefuroxime. It’s also used when your dog is allergic to penicillin-based drugs.
If your dog has had bad reactions to antibiotics before, or if they have kidney disease, your vet will check blood work before starting cefuroxime. Some breeds, like Greyhounds, are more sensitive to certain drugs. Always tell your vet about any other meds your dog takes—like NSAIDs or antacids—because interactions can happen. And never assume a dog’s infection is bacterial. Viral infections, allergies, or parasites won’t respond to antibiotics at all.
What you’ll find below are real comparisons and practical guides from dog owners and vets. You’ll see how cefuroxime stacks up against other antibiotics, what side effects to watch for, how to tell if it’s working, and when to ask for a second opinion. These posts don’t replace your vet—but they help you ask the right questions and understand the choices in front of you.
