Hi Debbie, its strange that they both have this, sounds like your boy had the bloody poos after a diet change? I’d say he’s probably sensitive to an ingredient in the Hills I/d……
Hills make 2 different I/d formulas for the stomach & bowel, vets normally put them on the I/d Gastrointestinal health at first, but the insoluble fiber is high in the I/d Gastro, also the Hills Z/d has very high insoluble fiber & corn starch as well if you can take back the I/d food & get the I/d Gi Restore Low Fat for your girl the fiber is lower at 1.7% or try the Royal Canine Intestinal Low Fat the fiber is lower at 1.7% & its a soluble fiber & the Royal Canine Low Fat doesn’t have corn or corn gluten, all the Hills diets have corn, corn gluten meal, corn starch etc they may both need to be on different diets…
My boy was pooing blood, light red, he has Colitis, he was sensitive to an ingredient that I was feeding him in his cooked meal at the time, he suffers from food intolerances, he was put on the Royal Canine Hypoallergenic at the time but look for the R/C Hypoallergenic that has a lower fat, I think Purina vet diet makes a Hypoallergenic as well for your boy…In America the R/C is a bit different, the Australian R/C Hypoallergenic is 19% fat which caused another problem, Pancreatitis.. change vet diets to Royal Canine not Hills or another vet diet & ask vet about Tylan Powder its milder then the Metronidazole (Antibiotic for bowel) the Tylan powder taste awful & is very bitter, so a lot of people put the 1/8th -1/2 teaspoon in those empty capsule you buy at chemist & make the Tylan powder capsule up, its easy you get an empty shoe box, make holes for the capsules, open the capsules & put the bigger end in box, then I used a cake piping end as a funnel & made up the Tylan capsules, its online & you can buy the kit on Amazon.. you give the Tylan powder with meal, every 12 hours, Patches poos firmed up with in 2 days also look at S.I.B.O Small Intestine Bacteria Overgrowth, they recommend that the dog is on either Metronidazole or Tylan powder for 28-45 days to get rid of the bacteria in the bowel..
