Hi again, and thanks for your additional information.
Garlic is not toxic to dogs in small amounts, but if he chewed up the whole bottle, he definitely ingested more than a small amount. I'm not surprised he's very thirsty. While garlic powder is considered less toxic than actual garlic cloves, it may still be toxic, and a vet visit, if he begins to exhibit symptoms like vomiting, diarrhea, difficulty breathing, would be your best course of action.
Onions and garlic contain the toxic ingredient thiosulphate. Onions are more of a danger.
Pets affected by onion toxicity will develop haemolytic anaemia, where the pet’s red blood cells burst while circulating in its body. Symptoms include Hemolytic Anemia, labored breathing, liver damage, vomiting, diarrhea, discolored urine.
The poisoning occurs a few days after the pet has eaten the onion. All forms of onion can be a problem including dehydrated onions, raw onions, cooked onions and table scraps containing cooked onions and/or garlic. Left over pizza, Chinese dishes and commercial baby food containing onion, sometimes fed as a supplement to young pets, can cause illness.
While garlic also contains the toxic ingredient thiosulphate, it seems that garlic is less toxic and large amounts would need to be eaten to cause illness.

Monitor him tonight, and allow him to drink as he wishes, and also give him some extra food, to try to absorb the garlic powder. If he'll eat very burnt toast, the charcoal in the burnt part will also help neutralize the toxins from the garlic powder.
I'm also concerned about the plastic bottle; if he chewed it up and ingested these small pieces, which may have sharp edges, it could cause internal bleeding in his digestive/intestinal tract, so this is another reason to see the vet, as soon as possible.
I hope your dog will be fine!
