Overview
['This soft gel supplement from Doctor By is built around propolis extract powder along with a proprietary ingredient called TF-343 and tapioca, packaged in an 8.5 ounce container. It is formulated to support bronchial health and respiratory health in dogs, and the chicken flavor is meant to make it easy to give as a treat rather than a pill you have to hide in food.', 'The label targets small breed dogs dealing with dry, wet, or barky coughing, positioning it as a wellness supplement rather than a medical treatment. Because coughing in dogs can have many causes, from kennel cough to more serious airway or heart issues, this kind of product works best alongside a vet visit rather than instead of one.', 'At $34.49, it sits in the mid to upper range for a respiratory supplement, and with 463 reviews and a 4.0 star rating plus roughly 600 bought in the past month, it has a reasonable track record without being one of the runaway bestsellers in this category.']

Performance notes
The soft gel form with propolis extract and tapioca is designed to be palatable enough that dogs take it without a fight, which matters for a respiratory formula you may need to give regularly. The chicken flavor and treat-like texture set it apart from powders or liquids that need to be mixed into food.
What buyers say
With 463 reviews averaging 4.0 stars and around 600 units bought in the past month, this product has steady but modest traction, the kind of numbers you would expect from a specialty respiratory supplement rather than a mainstream best seller.
No. This is a supplement formulated to support bronchial and respiratory health, not a medical treatment, and it is not veterinary advice. If your dog has a persistent, worsening, or severe cough, see a vet to rule out kennel cough, heart disease, or other causes.
Is this supplement made for all dog sizes?
The label targets small breed dogs specifically. If you have a medium or large dog, check with your vet or the manufacturer before using it, since the guidance here is aimed at smaller body weights.
What is the main active ingredient?
The label lists propolis extract powder along with a proprietary ingredient called TF-343 and tapioca as the base of the soft gel.
