COVID-19 Updates: as of May 2021
At Valley Veterinary Hospital and Cascade East Animal Clinic, we are committed to providing a safe environment for you, your pet, and our team members during the COVID-19(coronavirus) pandemic.
There is currently no evidence that pets become sick from COVID-19, nor that they can transmit it to other animals.
We have implemented additional cleaning and sanitizing procedures at our hospitals.
We ask our clients to follow these guidelines:
1. We are currently using curbside check-in service until further notice. When you arrive, you will see a phone number and parking spot number to call in (please NO texts) to notify us you have arrived. (Please be patient, our 3 receptionists are working as efficiently as possible to answer phones and assist other clients.)
2. We have limited lobby capacity of 4 people to maintain social distancing. We attempt to give priority to clients who have circumstances that necessitate lobby use. We ask that you please wait for a staff member to invite you in to the lobby and wear a mask inside our building.
3. We currently are unable to allow owners in exam rooms with their pets.
4. If you are sick, have a fever or a cough, please communicate with us by phone, and kindly do not enter our facility. We can discuss options for getting your pet seen.
Thank you for your patience during this time; we are doing our best to promote a safe environment for our clients and staff. We want to provide the best patient care possible and make your experience here as comfortable as possible. We look forward to being able to ease these guidelines when it is deemed safe to do so.
EQUINE INTERNAL PARASITE MANAGEMENT AND DEWORMING GUIDE
Internal parasites are still a major health concern in horses. Preventable illness and death due to these "worms" is still being seen by our veterinarians. Also, in recent years the concern has become parasites that escape traditional deworming methods?encysted small strongyles and tapeworms.
At the same time, concern has arisen with potential development of resistance to traditional dewormers in large animal species, including horses. In some cases, horses are being "over-dewormed."
For these reasons, newer recommendations focus on "targeted deworming," based on fecal egg counts of parasites in individual horses. We now know that with different equine immune systems, parasite susceptibility varies from horse to horse. Twenty percent of horses in a herd account for 80% of the parasites shed onto the ground. The goal is to identify equine "shedders" (often young horses or those with stressed immune systems) through fecal testing. Testing also allows you to determine how effective your deworming medication is on your horses' parasites, and how often treatment is needed. In the long run, this can save you time and money and helps slow down the onset of resistance to deworming medications.
1. Since fecal testing will NOT identify encysted small strongyle larvae and is limited in detecting tapeworms, these parasites should be targeted 1-2 times annually.
-Tapeworms (acquired through grazing or consuming hay): use Praziquantel, available in combination with ivermectin (Zimectrin Gold), at least once yearly (at least one treatment Oct 1-Nov 1, after the first frost). Zimectrin Gold is also effective against virtually all equine internal parasites, including roundworms, tapeworms, strongyles, and bots.
-Encysted small strongyles can cause a deadly condition in winter called larval cyathostominosis characterized by diarrhea and weight loss. Therefore we recommend targeting encysted small strongyles in late fall/early winter (Jan 1) with the most effective treatment, moxidectin, (Quest, or Quest Plus). Moxidectin is also effective against roundworms, strongyles, and bots. We no longer recommend fenbendazole (Panacur Powerpack
2. Fecal testing identifies strongyle, roundworms, pinworms, and other parasite eggs. We use the most current laboratory procedures in detecting these parasites (sugar-centrifugation/flotation).
a) To obtain a pretreatment baseline egg count, perform a fecal around 12-16 weeks after the last deworming. A very low number of parasite eggs are acceptable, but at a certain threshold we will recommend deworming. The veterinarian will also take into account your horse's age, environment, and herd size in this recommendation.
b) To assess the effectiveness of a recent deworming, perform a post-treatment fecal testing 2 -3 weeks after a deworming treatment. This may help identify any potential deworming resistance on your farm.
c) After we determine the frequency of deworming needed for a specific horse, follow-up pre-treatment fecal testing annually is recommended.
d) To collect a sample, collect several tablespoons of fresh manure and bring it to the clinic double ziplock bagged within 24 hrs. Refrigeration is advised if sample in not brought in immediately.
3. If you choose not to have fecal testing done, we recommend deworming your horse every 3-4 months with a moxidectin or ivermectin product, taking into account the guidelines in (#1) above. Keep in mind that a fecal egg count test is less expensive than the cost of two deworming treatments! (Fecal: $26.75, additional horses $20.25 each when submitted at the same time). A common scenario is that testing reveals that less deworming treatments are necessary for your horse, and that saves time and money.
4. Specific risk category groups:
- Young horses
Horses less than 5 years of age have higher parasite rates. Yearlings and weanlings are most susceptible. All foals should receive their first deworming by 2 months of age and may be dewormed with an ivermectin or pyrantel product.
Most commercially available dewormers are labeled safe to use in pregnant mares. We recommend the spring deworming treatment be given 4-6 weeks prior to foaling, as this will help to protect the foal.
-Newly acquired horses
They can have a big impact on parasite levels in your pasture and herd. Prevent problems by quarantining until fecal egg testing and deworming can be completed.
5. Other parasite management recommendations:
-Pasture management (also contact Kittitas Co Conservation District)
Manure should be collected and/or dispersed frequently. Grazing more than 1 horse per 2 acres results in higher parasite levels.
Interesting Fact: moxidectin, the ingredient in Quest Deworming, is non-toxic to "fecal fauna", such as dung beetles, which are beneficial to pastures. Other dewormers can have a negative effect on these beneficial organisms.
Graze yearlings and weanlings on separate pastures from older horses.
Under dosing deworming medications is a frequent problem that allows resistance to develop more rapidly. If in doubt of your horse's weight, ask us for estimation, or use a weight tape.
