Jo said she suspected Baxter had been bitten by an adder during the walk – which took place along a bridge near the RAF Valley runway located on the island – on 31 March because of his laboured breathing, taut stomach and bloodshot eyes.
The vet found a small mark but no swelling, which is a common symptom of an adder bite, so was unable to confirm it was the cause.
Baxter was not given anti-venom over concerns about his breathing and possible side effects, which can include anaphylaxis.
His owner planned to take him to a facility for overnight care not available on the island but before she could collect him, she received a call saying Baxter’s heart had stopped.
“I had only had Baxter for two years, it was tragic,” she said.
