Improved Energy

I have two different-energy dogs who are about 13 years old. My lower-energy beagle mix reacted well to this food and was more active in playtime. My higher-energy Border Collie mix dog reacted with anxious behavior for a month and was destructive when left alone at home (which she has done on other high protein foods, too) so I put her back on Science Diet 7+ Chicken and Rice.

Great dog food

This food is great for senior dogs. It’s not as hard for them to eat. Love chewy. I can always depend on them for promptness.

My Dog Loves This!!

I wanted to give my dog a little variety in her diet and not give her just beef all of the time. She is 8+ years old, so she needs a senior diet. She dove right into this the first time I gave it to her. She loves it and always wants more.

Perfect bite size for our fourteen and one half year old Brittany Spaniel Jack Russel dog. Have had Mia on a Hills Science Diet since we adopted her eleven years ago. There is a formula for every need

Made my dog constipated

I don’t know what’s wrong with this food or what ingredient made it almost impossible for my dog to poop. I have a 7 year old lab. She walks religiously every morning and evening at the same time. In 7 years she always pooped in the am and pm. When she started with this food, I noticed a struggle to poop making me late for work or having to hire a dog walker to go see her to make her poop. The size of the poop? Extremely small for such a large dog. Even after walking for over 1 hour, she still will not poop. In the beginning I thought it was the adjustment to the new food. Now, almost a month I can honestly say this was the worst food I’ve ever given her and would never purchase it again.

dog won't eat this food

I'm really bummed....we had the 7+ perfect digestion dry food and my dog stopped eating it, and had no interest after a while. and stopped eating it. He has absolutely no interest in this either. and won't eat it. He has not been a picky eater until I started feeding him Hills after he needed a prescription recipe for a short time. It looks like I'll have to try a different brand of senior food or just feed him the 7+ canned beef stew since he loves that. I know Hills is an excellent brand but I wish they had beef in the dry food recipes that might help.
