This is my dog, Mate, a 7-year-old border collie. Last week he had two seizures and after a test, the doctors discovered epilepsy, but now he is medicated. The medicine is very strong and he is unhappy and slow. When he walks, he hits the walls and he can’t jump on the bed or sofa as his legs are very weak. Hola, no esta mal. 7-year-old es un adjetivo de border collie y los adjetivos nunca son plurales. A test - una prueba. No es específico. Sigue practicando. Saludos desde España. Simón.
