K9 Advantix II Medium 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 Medium 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 11-20 lbs. to use K9 Advantix II Medium Dog. For the ultimate convenience in care, K9 Advantix II is available over the counter – no prescription needed. And, you can stock up with 2-dose, 4-dose and 6-dose packs so you never miss a monthly treatment. 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 Medium 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. The number of spots depends on the size and weight of your dog (please refer to the product label). At each spot, part the hair until skin is visible. Place the tip of the tube on the skin and gently squeeze to expel a portion of the solution on the skin. Do not apply an excessive amount of solution at any one spot that could cause some of the solution to run off the side of the dog. Do not get this product in your dog’s eyes, or allow your dog to ingest this product.

Hard to Beat for the Price
Size: 10 Wide, Color: Tan Leather Burnished
I purchased these for a business trip to Italy and wore them daily for the two weeks that I was there, during which I walked extensively. For me, there was a break-in period of a few days; before it loosens up, it will bite your heel, so I recommend wearing bandages or heel pads initially. Following the break-in, it's a very comfortable shoe and has served me well. I purchased a wide, and for this shoe, I found the width agreeable; in my experience, Cole Haan wide widths tend to be hit or miss (i.e., a wide is sometimes not all that wide). In terms of durability, I would not expect these to remain in good condition for more than a year if you wear them daily. The leather is not of high quality, but it's acceptable for the price. Expect them to crease very quickly if not using shoe trees. That doesn't bother me, but I know some find it objectionable. All in all, I like them and would buy them again. It's a comfortable alternative to traditional dress shoes for the office and works equally well for casual wear. Most higher quality options cost at least two or three times as much, and many are unavailable in a wide.

My favorite shoes
Size: 14 Wide, Color: White Leather
I’ve probably purchased like 40 pairs of these shoes or more. By far my favorite white sneaker. I have a large foot so the bigger sizes are appreciated. They’re versatile, literally go with anything and they are true to size. At a certain point they start to show wear and you can’t dress them up, but they last as a regular sneaker for a long time afterwards. I try to nab them on sale when they drop to $50-$70, absolute steal at that price point.

Clean Look, Super Comfortable – Instantly a Favorite
Size: 9.5, Color: White Leather
These sneakers are exactly what I was looking for—sleek, minimal, and incredibly comfortable right out of the box. The white leather looks sharp and pairs easily with everything from jeans to chinos, even dressed-down office wear. What surprised me most was the comfort. The sole is lightweight with just the right amount of cushioning, making them perfect for walking around all day. I’ve worn them on long city days and never felt sore or tired. They fit true to size (I’m a 9.5 and they’re spot on), and the quality feels premium. If you're after a versatile white sneaker that balances style and comfort, these are 100% worth it.
