Unless your horse has a very thin tail, there's no way to get a perfect finish. It will take more than one cut, and that means edges and uneven ends. If you have a lot to cut off, you can start with scissors, but finish with hand trimmers. Holding the trimmers upside down, you can cut along the bottom of the tail.
Intramammary antibiotic tubes are the most common treatment for mild and moderate cases of mastitis and are usually given without knowing the type of bacteria that is causing the infection (Hoe and Ruegg, 2006; Oliviera and Ruegg, 2014).
Anthelminthic medications (drugs that rid the body of parasitic worms), such as albendazole and mebendazole, are the drugs of choice for treatment of hookworm infections. Infections are generally treated for 1-3 days.
