It isn't difficult to remove a tick from a dog. To do so, you need latex gloves, tweezers, rubbing alcohol antibiotic ointment. 
- Put on the latex gloves to prevent coming in contact with the tick yourself and possibly contracting a tick-borne disease. 
- Apply a bit of rubbing alcohol to the tick and the surrounding area. 
- Grasp the tick with the tweezers as close to the pet's skin as possible.
- Pull the tick out slowly without squeezing. You don't want the head to remain attached if you can avoid it, and you don't want to squeeze any of the tick's fluids into your pet's body.
- Place the tick in a jar of rubbing alcohol.
- Clean the site where the tick was removed using rubbing alcohol.
- Apply antibiotic cream.
Make a note of the date that the tick bite occurred in case any symptoms of tick-borne diseases develop.  Lameness, swollen joints or lymph nodes, fatigue, loss of appetite and neurological problems are possible signs of tick-borne disease.  Infection or irritation may also occur at the site of the tick bite. If any of these symptoms or signs develop, take your dog to the veterinarian for evaluation and possible treatment. Bring the jar containing the tick in case the vet needs it for identification or testing purposes.
