In a tiny dog like a Chihuahua, this is definitely a concern. There are three main ingredients in Vicks DayQuil - acetaminophen, dextromethorphan, and phenylephrine. The acetaminophen can cause liver problems in small dogs depending on how much of the liquid he actually ingested, and phenylephrine can cause cardiac arrhythmias and blood pressure issues. I would recommend taking Blizzard to a vet right away - if he just ate it recently, your vet may be able to induce vomiting and give activated charcoal to help limit how much he absorbs.
