3. Reduced Appetite
In many cases, you also have a loss of appetite. This is a fairly common symptom of the illness in humans, but it is the primary symptom when it comes to hookworm infection in dogs. If your pet has a hookworm infection, one of the first things that you will notice is that they are unwilling to you – even if it is food that they have always loved in the past.
Having a reduced appetite can also be a symptom of hookworm with humans as well. You may notice that you are not eating as much as he used to, that you do not enjoy foods the same way that you did before and that you are losing weight because you are not eating as much as you used to. Loss of appetite is actually a pretty common sign among many illnesses out there, so you do want to get checked out if you find yourself with the symptom, but it could be attributed to hookworm.
