PetAg 

PetAg brings practical nutrition and care to homes and rescues, focusing on formulas that help newborn animals grow strong, support recovery and keep pets moving with steady energy. From essentials such as milk replacers, targeted probiotics and high-calorie boosters, every PetAg product is made for real animals and everyday routines – and we’re proud to offer a range of the brand’s products at Tractor Supply. 

Supporting Active Animals with Robust Formulas 

Since 1930, PetAg has supported animals at every stage with practical nutrition backed by real research. Its product lines, including KMR, Esbilac, Bene-Bac and Dyne, form the core of that work, helping caregivers move from first feedings to senior care with confidence. Each formula is built to pull its weight, so you can focus on animals in front of you and enjoy Life Out Here alongside them. 

PetAg products provide clear directions and contain purposeful ingredients, helping to turn important to-do items into repeatable routines. From the first night home to the next training cycle, the brand aims to make each step practical, safe and easy to follow. When care gets more complex, this brand’s steady approach helps you act quickly and feel confident about what comes next. 

About Our PetAg Selection 

Our PetAg pet and animal pharmacy selection is designed to meet the real needs of animal owners. We have the core essentials for bottle babies, a trusted puppy milk replacer line, a probiotic range for digestive balance, high-calorie support for added energy and grooming solutions for coat comfort and appearance. Our mix of offerings makes it easier to prep for the next feeding, training class, trail day or quiet night beside the fire. 

From nurseries to kennels to tack rooms, our PetAg products are intended to keep animals healthy throughout their entire lives. Start with the everyday pieces you use most, and then add targeted helpers as seasons change or animals grow. A thoughtfully stocked shelf now means smoother care later for the pets and livestock you look after. 

Dog Pharmacy  

Dogs shift roles throughout any week, and PetAg covers the arc from growth to recovery. You’ll see focused calories to give them energy for working days, probiotics for gut balance and grooming standbys that keep skin comfortable. Choose what fits your dog’s job today and set the stage for tomorrow’s miles. As training ramps up or seasons turn, our PetAg dog pharmacy section points you to the dog care essentials that earn their spot on your shelf. 

Dog Supplements 

When energy dips or workloads rise, a high-calorie liquid supplement or an easy-feed, high-calorie gel provides dense nutrition for working dogs, seniors, expectant moms and picky eaters. Discover PetAg dog supplements that support bone and tendon development during fast growth, helping young dogs build the frame they need for an active life. Keep these standbys ready during busy weeks and keep your partner fueled through long days and steady work. 

Dog Digestive Products 

A multi-strain probiotic helps maintain normal digestion during common stress points, including weaning, travel and diet change. A consistent gut often brings calmer behavior and better appetite, which makes PetAg dog digestive care easier for you and more comfortable for your dog. Use a simple probiotic plan around transitions, so mealtimes stay predictable and recovery stays on schedule. 

Dog Skin and Allergy Care 

Comfort for the coat starts with gentle grooming and balanced nutrition. Oatmeal formulas help soothe sensitive skin at bath time, while omega fatty acids and supportive vitamins support skin and immune health from the inside. Pair regular baths with the right PetAg dog skin and allergy nutrients to cut down on itch and keep coats bright through the season. 

Cat Pharmacy 

Powdered and ready-to-feed formulas anchor bottle care for kittens, with additional choices to rely on when you need alternatives. A probiotic powder or gel supports digestive balance during weaning or transport, and a high-calorie gel helps picky or recovering cats meet daily needs. Set up your bottle station once with the right PetAg cat pharmacy products, and repeat the rhythm each feeding window, so fragile starts turn into strong growth. 

Livestock and Farm Pharmacy 

Barn work brings surprises, so a prepared supply matters. A high-calorie liquid from our PetAg livestock and farm pharmacy selection supports weight and energy during recovery or show prep, while milk matrix formulas and nursing kits extend care to calves, kids and other bottle babies. Use a barn-ready probiotic when stress runs high so animals settle after a haul or a pen change.
