Be Careful with Gel Ice Wraps Around Pets and Kids

Don't let this happen to you. Before your dog or child bits into a gel ice pack replace all your with food grade ice packs like those from Pro Ice. Their ice packs are made from same formula used to ship frozen foods and are completely for human or pet consumption.

Puppy Bit Into a Gel Ice Pack

He is a 4 month old shih tzu
He bit into the packet but by the looks of the packet, it doesn't seem like he may have ingested any of the plastic
HOWEVER, we do not know for sure if he ingested any of the blue gel substance inside the packet.
The brand of the gel ice pack was "Rapid Relief Hot/Cold Gel Pack" and it said "non toxic"
I think he may have ingested some seeing as he is young and likes to eat everything he sees.
Now I need to know what are some symptoms I should expect to see
He has jus eaten his dinner and drank water and so far he hasn't done anything unusual
What should I do??
