URGENT Public Service Notice to Pet Owners and Livestock Farmers!
We want to inform you about a serious outbreak that has recently been confirmed. The first detection of New World Screwworm (NWS) has occurred in Zavala County, Texas, affecting a 3-week-old calf in the umbilical area. It's crucial to note that this pest poses a risk not only to livestock but also to dogs and cats.
To help protect your pets from the potential threat of a screwworm infection, we recommend using Credelio for dogs and NexGard Combo for cats. These flea and tick preventatives can aid in preventing screwworm infections and keep your furry friends safe.
For livestock owners, staying informed about the signs of NWS and implementing preventative measures is essential. Being proactive with all your pets and livestock can help minimize the risk. Our staff is on standby and will update as this develops.
Open until 5:00 PM, if you have any questions or concerns, please contact Merritt Animal Clinic at 479-229-2600. We are here to support you and your pets!
