Size: Large Bar (For Dogs Over 30lbs) Frank trots up to Princess, and to your embarrassment, greets her by sniffing her bum. Franks just saying hello and Princess returns the favor. Youre seriously considering sitting Frank down for a talk, but then Spike walks up and they too greet each other butt first. Why do they do that Each dog (and cat, actually) has a distinct smell emitted from their anal gland fluids. This anal gland fluid is housed in anal sacs, little pouches of fluid on either side of the anus, that are expressed when firm waste passes through. When everything is going well, youve got a happy, butt-sniffing animal (yay!) but when the bowels arent working the way they should, youve got symptoms like a scooting dog, loose stool or even constipation. You know a dog scoot when you see one. Its your pups attempt to scratch and relieve those pesky anal sac issues. This is where Scooters Butt Bars can help. Feeding natural sources of fiber, like those found in our butt bars, can help dogs make regular, firm stool. With regular, firm stool your dogs anal sacs are expressed regularly, so he doesnt experience painful, itchy symptoms and you wont find him scooting on your new rug. Bowel issues can be caused by not only lack of fiber but from food intolerances or parasites (its a toxic world out there). Give your pup the support he needs to stay regular and maintain anal gland, digestive, and bowel health!
