Maisy’s family noticed something wasn’t right. Their energetic Border Collie suddenly seemed uncomfortable, painful, and occasionally disoriented.
After referral and a series of investigations, imaging revealed suspicious changes in her lung and around her heart. Although antibiotics helped her feel much better, follow-up scans suggested there was still an underlying problem.
Further testing pointed toward a surprising suspect: a migrating grass seed. 🌱
A CT scan identified a large lesion between Maisy’s heart and lung, and surgery was performed to uncover the cause. What did we find?
👉 Two grass seeds lodged in the tissues surrounding her heart (pericardium) and lung.
The infected tissue and foreign material were successfully removed, and after a short recovery, Maisy was back to doing what Border Collies do best, being full of energy! 🐕💨
Grass seeds may look harmless, but their barbed structure allows them to travel through the body, sometimes ending up in the most unexpected places. They can cause infections, pain, and confusing symptoms that can be difficult to track down.
Thankfully, Maisy’s story has a happy ending, and she’s back to enjoying doggy daycare and all her favourite activities. ❤️
