Yesterday I decided to go for a hike with my dog. Towards the end of the hike I noticed he was covered in ticks. (I applied the Frontline Plus prior to going on the hike). When we got home I brushed him for a good while to try and get the ticks out of his coat. However, since then he has been licking his two front legs non-stop. He seems to be licking the one leg more than the other and I have a feeling a "hot spot" is going to form. My question is should I take him to the vet today? This is my first dog and I'm just a little unsure of what to do.
