Resistance to horse wormers is becoming more widespread and it is therefore vitally important to target worming as necessary to prevent further problems in the future.
It is also really important to ensure that your horse is receiving the correct dose of wormer, as under dosing may add to resistance, and over dosing may occasionally cause health problems, although this is very rare.
Weight can be difficult to estimate, and it is often surprising how heavy some horses actually are! Ideally, a weighbridge should be used to provide an accurate measurement, however if this is not possible then a weigh tape should be used to give a guide. The weighbridge at the practice is usually available throughout the day.
