Acquired immunity

Explanation:

Acquired immunity is a type of immunity that we develop when we get exposed to some antigens. Our immune systems can build a defense against those antigens and next time when we encounter those same antigens our body will know how to react. This immunity builds up over time in order to have an answer ready when a threat presents itself.

all the above is what i would say

if you think your dog may have been exposed to a toxin, the best thing to do is to check the label of the item you think your pet ingested. read the information about toxicity. often, but not always, the information on packaging regarding children is relevant to dogs and some manufacturers even discuss dog toxicity. if there is an 800 number on the package – call them! it’s also recommended that you call your veterinarian to confirm the recommendations. if you go to your veterinarian, take all packaging and any information you have on the product.
