Vetox- Doxy Forte- Doxycycline Hyclate USP- 100mg /Tab

Doxycycline is an antibiotic that blocks the growth of some types of bacteria. Once the bacteria stop growing, your dog’s immune system can cure the infection. Doxycycline doesn’t work against all bacteria, though.
Veterinarians use doxycycline to treat certain bacterial infections in dogs, including:
 
Tick-borne infections (Lyme disease, Rocky Mountain spotted fever, and others)
Kennel cough and other respiratory infections
Some urinary tract infections
Dental disease
Leptospirosis
 
 
Veterinarians also prescribe doxycycline for dogs receiving heartworm treatment. Heartworms are parasites that affect the heart and lungs of infected dogs. Heartworms often contain Wolbachia bacteria, which worsen inflammation associated with heartworm disease. Treating a heartworm-infected dog with doxycycline kills Wolbachia inside the heartworms. This reduces signs of heartworm disease and makes heartworm treatment less risky.
 
Finally, veterinarians may combine doxycycline with other medications to treat autoimmune skin diseases. For example, discoid lupus erythematosus in dogs is often treated with doxycycline.
