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.

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.

Great suit, but size up
Size: Large, Color: Black, Size: Large, Color: Black
This set comes with a jacket, pants, extra buttons, and a bow tie with an easy clip to remove it. The suit itself is really nice and I love the pattern, however, I thought I purchased a XXL, but seemed to have ordered a L instead. Not quite sure how that happened, but suffice to say, he could not fit the suit. He is normally an L in pants, so based on the fit, we would have needed to size up anyways. He couldn't fit his leg in the pants or his arm in the jacket. I automatically size up on items like this because you can take clothes in, but can't take them out if there is not enough cloth. The suit pants are not lined, but you can see that they did leave room for the legs to be let out. Perhaps if we have the pants let out, he would be able to wear the pants. The jacket is fully lined and it comes with two inside pockets, one can be buttoned. I cannot tell if the jacket has room for alterations, but I might have him fitted for it just to see. It comes with a slit on the back of the jacket, so it has that going for it from a quality standpoint. It does come folded so you have iron or dry clean it before wearing. The quality is good for the most part. There are some threads coming out of the bow tie, but that's all I seen that is less the good. I'm giving it four star based solo on it's look and feel. Of course, I can't comment on the fit. For around $80, I definitely think it's worth checking out for a school semi-formal or fancy dinner out. It might be a little lightweight for a higher end event. Did I say I love the pattern?

Stylish look and great value for special occasions
Size: X-Large, Color: Blue, Size: X-Large, Color: Blue
This suit looks really good in person. The pattern adds a nice touch that makes it stand out without looking too flashy. It is a great option for events like weddings, parties, or prom where you want something a bit different from a basic suit. The fit is slim and modern, giving a clean and sharp look when worn. It feels comfortable enough for a few hours, and the overall shape looks more tailored than expected for the price. The jacket sits well, and the pants match nicely to complete the set. The material is lightweight and decent for occasional use. It does not feel like a premium suit, but it looks good and photographs well, which is what matters for events. The bow tie included is a nice extra and helps complete the outfit without needing to buy more pieces. It may need a quick steam or ironing out of the package to look its best. Also, checking the size chart is important to get the right fit. For the price, this is a very good value. You get a full outfit that looks stylish and put together without spending too much. Great option if you need something affordable for special occasions.
