Dog & Cat Antibiotics & Respiratory Medicine | Wholesale & OEM Manufacturer

Antibiotics & respiratory medicine for pets refer to antibacterial drugs formulated specifically for companion animals like dogs and cats, offered in large quantities or bulk packaging. These products cater primarily to business buyers such as pet product brands, distributors, and veterinary clinics. With over two decades of experience in veterinary pharmaceuticals, WERVIC has developed a broad portfolio of bulk antibiotics and offers flexible options for formula customization and tailored packaging to meet diverse client needs.

What Are Dog & Cat Antibiotics Used For?

Antibiotics for dogs and cats are prescription-class antibacterial medicines formulated to treat infections caused by susceptible bacteria. They are not effective against viral infections — a critical distinction for distributors communicating accurate product positioning to veterinary clinic customers.
In companion animal practice, antibiotics are most commonly indicated for three clinical scenarios: primary bacterial infections, secondary bacterial infections complicating a viral illness (the most common respiratory use case), and prophylactic use around surgical procedures.
Respiratory disease is one of the highest-frequency antibiotic use cases in veterinary practice. When a dog or cat contracts a viral respiratory illness — canine distemper, kennel cough, feline viral rhinotracheitis — the damaged airway mucosa becomes vulnerable to secondary bacterial invasion. This secondary infection is what antibiotics treat, and it is what drives sustained demand for this product category across veterinary clinics globally.

Three infection types this range covers:

Respiratory Infections

Secondary bacterial pneumonia, bronchitis, mycoplasma and chlamydia infections in the upper and lower respiratory tract of dogs and cats.

Skin & Soft Tissue Infections

Pyoderma, wound infections, abscesses, and folliculitis caused by susceptible gram-positive and gram-negative bacteria.

Urinary Tract Infections

Bacterial cystitis and pyelonephritis, one of the most commonly diagnosed conditions in female dogs and cats.

Product Range

Amoxicillin Chewable Tablets for Dogs & Cats

Broad-spectrum beta-lactam antibiotic in a palatable chewable format. Amoxicillin is among the most widely prescribed first-line antibiotics in companion animal veterinary medicine globally, with established efficacy against gram-positive and select gram-negative organisms.
Primary indications: Respiratory tract infections, skin and soft tissue infections, urinary tract infections, gastrointestinal bacterial infections.

OEM available: Custom flavoring (chicken, beef, liver), tablet size, packaging format.

Doxycycline Tablets for Dogs & Cats

Broad-spectrum tetracycline-class antibiotic with activity against a wide range of bacterial pathogens including intracellular organisms that beta-lactams cannot reach. One of the most clinically versatile antibiotics in veterinary medicine.
Primary indications: Respiratory infections (mycoplasma, chlamydia, Bordetella), tick-borne bacterial diseases (Ehrlichia, Anaplasma, Borrelia), skin infections, urinary tract infections, periodontal disease.
 Doxycycline's activity against tick-borne diseases is a major clinical differentiator from amoxicillin 
OEM available: Custom tablet strength, packaging, label.

Enrofloxacin Tablets & Capsules for Dogs & Cats

Fluoroquinolone-class antibiotic with potent bactericidal activity. High tissue penetration makes it particularly effective for deep or systemic infections where other antibiotic classes show limited distribution.
Primary indications: Gram-negative bacterial infections, respiratory infections, urinary tract infections, gastrointestinal infections, skin and soft tissue infections including deep pyoderma.

Important regulatory note for import buyers: Enrofloxacin use in cats requires careful dosing guidance — high doses have been associated with retinal toxicity in cats. Product labeling should reflect species-specific dosing instructions compliant with your target market's regulatory requirements. We provide appropriate labeling support.
OEM available: Tablets or capsules, custom strength, branding, packaging.

VET CARE DOCY 200

Broad-spectrum doxycycline-based formulation with enhanced bioavailability. Developed for distributors seeking a differentiated, branded antibiotic product positioned above standard generic doxycycline.
Primary indications: Respiratory infections, chlamydia, mycoplasma, tick-borne bacterial diseases. Full tetracycline-class spectrum with optimized absorption profile.

OEM available: Co-branding, custom packaging, market-specific label adaptation.

A Note on Antibiotic Resistance 

Antimicrobial resistance (AMR) is an increasing regulatory and clinical concern in both human and veterinary medicine globally. Responsible antibiotic supply involves:

Ensuring products are positioned as prescription-only where required by local regulation
Providing accurate species-specific dosing guidance on labels
Supporting downstream veterinary oversight rather than facilitating over-the-counter misuse

We manufacture to GMP standards with full traceability per batch. Our labeling support service ensures product claims and dosing instructions are aligned with your target market's regulatory framework, reducing import compliance risk for buyers in regulated markets.

Regulatory & Safety Notes 

Prescription status: Veterinary antibiotics are prescription-only medicines in most regulated markets (EU, UK, US, AU). Import requires appropriate pharmaceutical import licensing. We provide full technical documentation to support local registration.
Key safety notes to communicate downstream:

Complete the full antibiotic course — stopping early when symptoms resolve is the primary driver of treatment failure and resistance development
Do not use antibiotics to treat viral infections (colds, flu, most upper respiratory viral illnesses) — antibiotics have no effect on viruses
Enrofloxacin: use species-specific dosing in cats; avoid high doses
Doxycycline: administer with food or water to reduce GI irritation; avoid in pregnant animals and young growing animals (tetracyclines bind to developing bone and teeth)
Amoxicillin: contraindicated in animals with known penicillin hypersensitivity

Documentation provided per batch: Certificate of Analysis, GMP certificate, MSDS, packing list. Stability data and efficacy documentation available on request.

FAQ

What bacterial infections do your dog and cat antibiotics treat?
Respiratory tract infections (bronchitis, pneumonia, mycoplasma, chlamydia), skin and soft tissue infections, urinary tract infections, tick-borne bacterial diseases, and gastrointestinal bacterial infections — depending on the specific antibiotic class.
What is the difference between Amoxicillin, Doxycycline, and Enrofloxacin?
Amoxicillin (beta-lactam) is a broad-spectrum first-line antibiotic effective against gram-positive and some gram-negative bacteria. Doxycycline (tetracycline) adds coverage for intracellular organisms including mycoplasma, chlamydia, and tick-borne pathogens. Enrofloxacin (fluoroquinolone) is a second-line agent with strong gram-negative activity and high tissue penetration for deep infections.
Is OEM/private label available for all products in this category?
Yes. Custom branding, flavor, strength, dosage form, and packaging are available across all four products. Contact us with your target market and estimated volume for a project-specific proposal.
What documentation do you provide for import registration?
GMP certificate, Certificate of Analysis per batch, MSDS, product specification, stability data, and efficacy documentation. Our team supports registration dossier preparation for EU, UK, AU, Southeast Asia, Middle East, and LATAM markets.
Can I source multiple antibiotic classes from the same factory?
Yes. All three antibiotic classes (beta-lactam, tetracycline, fluoroquinolone) are manufactured at our GMP-certified facility, allowing you to build a complete first-line and second-line antibiotic range under a single supplier relationship.
Are these products suitable for both dogs and cats?
Yes, all products are indicated for dogs and cats with species-appropriate dosing. Enrofloxacin requires particular attention to cat-specific dosing guidelines — we provide market-appropriate labeling support.
