How can my dog gain weight on Hills z/d without upsetting his stomach?

Updated On September 23rd, 2025

Pet's info: Dog | Staffordshire Bull Terrier | Male | neutered | 8 years old

Thanks for quick reply Jessica. Diesel was 40kg but dropped rapidly to 28. Before being told it was acid reflux Diesel had a scan, blood tests & was put on Hills z/d. (Bloods were normal, scan showed slight inflammation & was given steroids for it) His appetite is good, he never had a loss of that, or any diarrhea. He only suffered with the vomiting & weight loss. He has z/d wet food still but I’d like to try getting a little weight back on him if possible without upsetting his stomach.

If Diesel has food sensitivities (usually z/d is to address this) but still isn't gaining weight on it, I'd definitely let his regular veterinarian know that he still isn't gaining. Your vet may recommend upping his current food for more caloric intake, or recommend adding in some supplements such as rice or chicken that are gentle on the stomach still (unless he is allergic to one of those ingredients.) I'd hesitate to just add in any OTC food as that may interfere with whatever caused the initial inflammation and make symptoms worse. It would be best to monitor this with your vet so that you can track his progress and see if upping the amount of food helps, or if he continues to not gain weight. Most vets will allow you to walk in without an appointment for a weekly weigh-in.
