- Symptoms: Excessive scratching, biting or licking of the skin, flea dirt (small black specks), and visible fleas in the fur.
- Treatment: Use veterinary-approved flea treatments such as topical spot-on treatments, oral medications, or flea collars. Ensure all pets in the household are treated simultaneously to prevent reinfestation.
- Prevention: Regular use of flea preventatives, maintaining a clean living environment, and treating your home and yard if needed.
1.2. Ticks
- Description: Ticks are arachnids that attach to pets to feed on their blood. They can transmit various diseases.
- Symptoms: Visible ticks on the skin, redness or swelling at the site of the bite, and in some cases, symptoms of tick-borne diseases such as fever or lethargy.
- Treatment: Remove ticks carefully using tick removal tools or tweezers. Consult your veterinarian for appropriate tick prevention and treatment options.
- Prevention: Use tick preventatives such as topical treatments, oral medications, or tick collars. Regularly check your pet for ticks, especially after outdoor activities.
