K9 Advantix II Large Dog is the veterinarian-recommended formula that helps defend your dog against five pests: fleas, ticks, mosquitoes, biting flies and lice. And unlike other treatments, K9 Advantix II kills and repels fleas, ticks and mosquitoes. K9 Advantix II topical treatment gets straight to work killing fleas on dogs within 12 hours of initial application. This formula stops existing flea infestations and prevents new ones by killing adult fleas on contact so they can’t lay eggs and they don’t have to bite your dog to die. Fleas, ticks, mosquitoes and other pests not only cause discomfort; they may also transmit disease. Monthly use of K9 Advantix II is important to protect your dog against fleas that may cause transmission of tapeworms. This formula also kills fleas which may cause Flea Allergy Dermatitis and flea bite anemia. That’s why K9 Advantix II Large Dog topical, spot-on formula makes application simple - going on in seconds. It's easier than a flea collar and there are no hard-to-swallow pills. You’ll also love that K9 Advantix II is fragrance-free and waterproof after 24 hours of application. Check the product label for information on application and potential side effects. K9 Advantix II pest protection is effective on both indoor and outdoor dogs. Your dog should be at least 7 weeks old and weigh to use K9 Advantix II Large Dog. For the ultimate convenience in care, K9 Advantix II is available over the counter – no prescription needed. Once K9 Advantix II is applied, your dog is ready to get right back to big-pup cuddles and racing around the park. K9 Advantix II Large Dog is a trademark of Elanco or its affiliates.

Directions for Use
Use only on dogs. DO NOT USE ON CATS or other animals. Do not apply to dogs weighing less than 4 lbs. Remove applicator tube from the package. Use scissors and peel down foil. Hold applicator tube in an upright position. Pull cap off tube. Turn cap around and place other end of cap back on tube. Twist cap to break seal, then remove cap from tube. The dog should be standing for easy application. Evenly apply entire contents of the tube along the top of the dog's back, from the shoulder down to the base of the tail.

Nice fitting good quality polo shirt
Color: White, Size: X-Large
The Esabel.C Zipper Golf Shirt is a sharp, modern upgrade for your active wardrobe, especially if you’re heading to the golf course or planning a trip to Mexico. The lightweight, moisture-wicking pique fabric is incredibly breathable, ensuring you stay cool and dry even during a high-energy day at Busch Gardens. I really appreciate the quarter-zip design over traditional buttons, as it gives the shirt a sleek, athletic look that fits right in with your other high-performance fitness gear. For an X-Large, the stretch in the material provides a comfortable, relaxed fit that allows for a full range of motion during your swing or a casual afternoon out. Its crisp white finish offers a versatile, professional aesthetic that pairs perfectly with the carbon fiber sunglasses we discussed for a polished summer look.

Nice fit, cooling fabric
Color: White, Size: Large
This is a fantastic golf shirt. I'm a medium build 6'3", 42" chest and the large fits me very well with plenty of room for movement but still giving me a nice trim look. The moisture-wicking material is soft and breathable, with a small bit of stretch. I really like the zipper style and contrasting collar. It's easy to care for with machine wash and dry, and comes out wrinkle-free. This shirt is very well made and is a great value - I highly recommend it.
