Quality feed

My senior shepherd had lost 10 lbs for no reason. Vet check all tests were good. A breeder friend said this is all she feeds her shepherds from pup to senior

My senior shepherd had lost 10 lbs for no reason. Vet check all tests were good. A breeder friend said this is all she feeds her shepherds from pup to senior. So I gave it a try. Ry put on 13 lbs and was acting youthful. I think, as a senior, her body just wasnt absorbing enough nutrients from her old food which she had done good on for years (taste of the wild salmon, purina onr lamb and royal canine). Its well worth the money to have her on solid gold wolf king gut health.

I'm Very Impressed

I have an 8 year old Newf/Great Pyr who has NEVER eaten dry kibble without some type of mix in. Same with my 9 year old toy Pom. Both of my dogs like to forage

I have an 8 year old Newf/Great Pyr who has NEVER eaten dry kibble without some type of mix in. Same with my 9 year old toy Pom. Both of my dogs like to forage for little "niblets" left by rabbits and squirrels and needless to say, they often have bouts of diarrhea. I spent a fortune for a couple years making their food and they had no stomach issues when I did this. However, I just couldn't maintain the cost and therefore tried other options throughout their lives. I've always purchased high quality food for the dogs. I've tried those with and without grain. I don't feel grains hurt my dogs because when I made their food, I used rice and pastas as the base. No allergies. As a result of the see saw of continuous vet bills for medications to help with diarrhea, I've constantly done research on the various dog foods. The dog food advisory helps somewhat but many of the foods they suggest, my dogs refused to eat. They had been eating Go! senior formula for a long time but again, the cost was difficult to maintain and they still had bouts with intestinal issues. After my large dog (she's 125 lbs) had been suffering from diarrhea and loose stools for over a week and homemade food was just a temporary fix, I decided to give this and a prebiotic/ probiotic supplement a try. She has been on this food now (after allowing her gut to clean itself out for a week) for four days as well as the supplement and she is doing great! This is the only food she has ever been given (and she has tried over the past 8 years at least 10 different, high quality brands) that she eats readily without anything added to it. It must taste good to her because her mouth is foaming with drool after eating! This never was a response to any other food, including the homemade. My little Pom (7 lbs) likes her gravy base so she gets a spoon of canned with this and she eats it all! She too has always pushed the dry kibble to the side, only wanting to eat the canned. I know this food contains pre/pro biotics to help with stomach issues and I am giving my large dog 1 a day instead of 3 and the little one 1/4 a day instead of 1. I've never had any food or supplement clear up my dog's gut so quickly. They did experience some mild gas the first day but no other issues. That has cleared up too. I'm excited to see how their health will improve as well as if their skin and fur have positive effects. I use Zesty Paws probiotic in case you are wondering. It's so hard to see your furry pals constantly sick and needing medications that do a poor job of stopping intestinal distress. I'm hoping that with this food and the supplement, my senior dogs will be healthier. I'll come back and tweak my review if anything changes.

I have a 5yo Doberman who is prone to dandruff and bad GI issues and a 1yo German Shepherd who was on a hydrolyzed diet for GI issues and skin issues but I just went through a divorce and my budget can’t afford $105 every 3 weeks right now. BUT this food is working amazing for the both of them!! Even my shepherd! He hasn’t had a single stomach issue, a little more gas than before but neither have the puking or diarrhea, bloating or food refusal. Skin issues have reduced. I’m very happy with this food. And they both LOVE it!

Immediately a fan favorite

I have 4 large breed dogs, ranging from 50 lbs and 4 years old to 85 lbs and a sturdy 13 years old. They are very hard to buy for, since everyone likes their food

I have 4 large breed dogs, ranging from 50 lbs and 4 years old to 85 lbs and a sturdy 13 years old. They are very hard to buy for, since everyone likes their food a little bit different. However, I didn't even have to open the bag and all 4 were hovering around trying to get some. We ended up adding some to their dinner after using some of the pellets as treats, and to say that it was well-received would be an understatement. They gleefully ate it and then begged for more. I think this will become a daily additive to their regime.

Optimal Health & Nutrition in Every Meal!

Solid Gold's Nutrient Boost Hund-N-Flocken Dog Food is one of their oldest recipes packed with nutrients, vitamins, probiotics, and more to give your pets the best

Solid Gold's Nutrient Boost Hund-N-Flocken Dog Food is one of their oldest recipes packed with nutrients, vitamins, probiotics, and more to give your pets the best of the best, in my opinion. The main flavor stems from the pasture raised lamb, in addition to other ingredients that are comprised of superfoods, whole grains, and living probiotics to name just a few! Thanks to this formula being loaded with ingredients that aid in the health of my dog's digestive & immune system, his energy levels, and his skin & coat, I can feel good about what I'm feeding him at meal times! Bonus: He loves the taste! In fact, I can't even get this food poured into his bowl before he starts trying to eat it as it's coming out of the bag. I've noticed in a rather short period of time that my dog's coat is more shiny, as well as thicker, & he just looks healthier overall since switching to this formula. Also, his energy levels & demeanor are more upbeat! In my opinion, it doesn't get any better in terms of dog food than a formula that's made with the best of ingredients and aids in the happiness & health of your pet! In addition, I know and trust the brand for their optimal quality & performance in their products, as well as their 40+ years of experience in the USA.

Solid Gold Dry Dog Food "The Best"

We have used Solid Gold Dry Dog Food since 1998. Solid Gold is the Best Dog Food out there! They were the first holistic dog food out there I believe. Their quality shows in our dog! We had an English Lab and she was with us from a new born pup until her passing after 15 years. Never had any health issues and always had a Beautiful Coat! Even our vet attributed her health and coat to the Solid Gold food! Now we have had our second Lab and she is going to be 10 years old in a few months. She is an American Lab from totaly different bloodlines and her coat is just as beautiful and she has remained healthy as well! Thank you Solid Gold!!! (We do miss the bagel biscuts)

Our frenchie mix did not care to eat this food. I have tried feeding her the lamb as well as salmon and she only eats small amounts...not required amount. She doesn't seem to like any of it. I also noticed that she has begun chewing on her skin and losing small amounts of hair. I am assuming its an allergic reaction to something in the solid gold dog food. We will be looking for a different brand.

My underweight senior dog was rapidly brought up to a healthy weight by another Solid Gold product (Barking at the Moon). We decided to go with this as a maintainace, as her vet said she was having difficulty abosorbing nutrients as she aged. She loved both options, and gobbles them up in rapid fashion. We are feeding her the amount on the bag, and her weight is steady, and her coat looks a lot better. Her gut tolerates well, no digestive issues.
