Hello. Icy will be OK, as long as she does not get any more acetaminophen, & she does not already receive other medications & does not have any underlying liver or kidney problems. Generally, toxicity is only noted if a pet ingests more than 100 mg/kg, which would be 1400 mg for a dog Icy's size. So a one time 650 mg will not be harmful to her unless she does have some of the issues I already mentioned. If this is the case, please call your regular veterinarian immediately. Thanks for using Petco Pet Education Center, formerly Petcoach.
