I am always so careful but i had peeled an onion and discarded the remains aas well as a few chunks about the size of a quarter. I was in the living room watching tv when i looked down and somehow she had a piece of the onion,,it was as big as a quarter it was one layer thick and she had chewed it good as small pieces had fallen off..I dont know if i have to rush her to vet or what..please advise
