Canker Tonic 500ml

Canker Tonic 500ml is a liquid treatment from MedPet for Trichomoniasis, commonly known as Crop Canker, in pigeons. It contains metronidazole and is designed for individual treatment by administering the measured dose directly with a stomach tube.

MedPet specifically recommends Canker Tonic for pigeon canker and lists it as safe to use during the racing season. Each 500ml bottle contains 4.5g metronidazole, an active ingredient widely used by MedPet in its pigeon canker treatment range.

For pigeon keepers who prefer targeted individual dosing rather than medicating an entire loft through the drinking water, Canker Tonic 500ml provides a practical treatment option.

What is Crop Canker?

Crop Canker is caused by Trichomonas infection and is one of the important health problems affecting pigeons. Infection can spread between birds, particularly where pigeons share drinking water, feeding areas or race baskets.

MedPet’s own racing-season information highlights shared water in race baskets as an important opportunity for Trichomonas transmission. Returning race birds and stray pigeons can therefore introduce infection into an otherwise healthy loft.

Active ingredient

Metronidazole: 4.5g per 500ml

Metronidazole is the active ingredient responsible for the product’s activity against Trichomonas. MedPet describes metronidazole as a safe and effective treatment for Crop Canker in pigeons.

Directions for use

Dosage: 10ml per pigeon, administered with a stomach tube.

Because this product is intended to be given directly into the crop using a stomach tube, correct administration technique is important. If you are not experienced with crop or stomach-tube dosing in pigeons, obtain guidance from an avian veterinarian or an experienced pigeon professional before administering the product.

Always follow the current container label and MedPet dosage instructions.

Use during the racing season

Canker Tonic 500ml is particularly useful for racing pigeon keepers because MedPet states that it is safe to use during the racing season.

MedPet’s racing-season guidance explains that individual treatment can be practical when only returning race birds need to be treated. This avoids having to medicate every pigeon in the loft through the drinking water when only selected birds require treatment.

MedPet’s 2025 racing-season guidance also notes that where resistant Canker has been identified, Canker Tonic may be administered on two consecutive days. Because treatment requirements can vary according to infection levels and resistance, veterinary testing is preferable where Canker continues to recur or does not respond as expected.

Why individual dosing can be useful

Medication delivered through drinking water depends on each bird consuming the correct amount of medicated water. Water intake can change with temperature, activity, illness and individual behaviour.

Direct dosing allows the pigeon keeper to know that a particular bird has received the intended measured quantity. This can be especially useful for valuable breeding birds, race birds, late-returning pigeons or individual birds requiring targeted treatment.

Canker management in a pigeon loft

Good Canker control should not rely only on repeated medication. MedPet recommends regular testing where possible because Trichomonas can persist or become more difficult to control where treatment is repeatedly used without confirming infection.

Clean drinking water, hygienic drinkers and sensible management of returning or stray pigeons can also help reduce opportunities for infection to spread through the loft.

Why choose Canker Tonic 500ml?

Canker Tonic 500ml offers pigeon keepers a direct and measurable way to treat Crop Canker. Instead of relying on variable drinking-water consumption, each selected pigeon can be individually dosed with the manufacturer’s recommended 10ml amount.

Its metronidazole formulation, suitability for racing-season use and convenient 500ml presentation make it particularly useful for pigeon lofts where individual Canker treatment forms part of the health-management programme.
