Inflammatory bowel disease (IBD) — the most common cause of chronic vomiting and diarrhoea in dogs and cats — is a diagnosis of exclusion and a lifelong management challenge. A retrospective study of 80 canine IBD cases found that at follow-up, only 26% were in sustained remission, 50% had intermittent signs despite management, and 13% were euthanised due to refractory disease. These are honest figures, and they reflect the inherent clinical challenge: IBD management involves dietary modification, pharmacological immunosuppression, and ongoing owner compliance with a protocol that must be maintained even when the pet appears well. A structured follow-up protocol that reinforces dietary compliance, monitors medication response, and catches flares early is the mechanism that shifts patients from the 50% category into the 26% sustained remission group.
Why IBD follow-up is fundamentally a dietary compliance problem
The research is specific: in a study of dogs with inflammatory protein-losing enteropathy (iPLE), poor dietary compliance — defined as frequent scavenging or changing from the recommended diet — was significantly associated with subsequent relapse in dogs that had achieved initial remission (p=0.01). Cornell University’s feline health resources make the same point about cats: “Keeping the disease in check requires strict compliance with dietary and medical therapies.” The dietary component of IBD management is not optional, and owners who understand this are significantly more likely to maintain it.
The treatment approach for IBD is multi-step: first a dietary trial (novel protein or hydrolysed protein diet), then antimicrobials if the response is incomplete, then immunosuppressive therapy with prednisolone or prednisone if dietary and antimicrobial management fails. Each step requires a defined trial period — typically 4–6 weeks for dietary response — and a follow-up assessment at the end of that period. Clinics that don’t have a structured follow-up at the end of each trial period are managing blind: they don’t know whether the dietary trial worked, partly worked, or failed to change anything.
The pharmacological component carries its own monitoring requirements. Prednisolone carries systemic side effects that worsen with dose and duration. Chlorambucil, used in cats with IBD not responding to glucocorticoids alone, requires haematological monitoring. Owners on immunosuppressive therapy need explicit guidance on infection risk and signs of over-immunosuppression.
The IBD follow-up timeline
| Timepoint | What to check | Red flags |
|---|---|---|
| 2–4 weeks post-dietary trial initiation | Any improvement in vomiting, diarrhoea frequency, appetite, weight, energy; dietary compliance — strict adherence, no other food sources, no flavoured medications or treats | No improvement after 4 weeks on appropriate elimination diet — proceed to next treatment step; owner has allowed dietary cheats |
| 6–8 weeks | Response to dietary trial or antimicrobials assessed; if on prednisolone — initial response, GI side effects, PU/PD, weight; dietary compliance still strict | Poor response to prednisolone — consider dose adjustment or addition of second immunosuppressant; owner stopping medication early |
| 3 months | Clinical remission status assessed, bloods if on chlorambucil (haematology) or long-term steroids (full biochemistry), weight, dietary compliance, dose reduction possible? | Relapse after initial response — investigate dietary compliance first; signs of GI ulceration from steroid therapy; neutropenia on chlorambucil |
| Every 3–6 months (stable) | Maintenance diet compliance, medication at lowest effective dose, weight, GI signs, owner quality of life assessment | Any significant flare — investigate dietary change or scavenging, infection, concurrent disease |
What to ask owners during IBD follow-up
- Has [pet name]‘s vomiting frequency improved — fewer episodes per week compared to before?
- Is the diarrhoea better — more formed stools, less frequent?
- Is [pet name] eating the prescribed elimination diet only — no other food, no treats, no flavoured medications?
- Have there been any incidents of scavenging — getting into rubbish, eating other pets’ food, or anything from the floor?
- Is [pet name]‘s weight stable or improving — are you seeing any weight gain?
- Is her energy and general comfort improving?
- Are you giving all the medications consistently — steroids, vitamins, or any other supplements?
- For dogs on steroids: has she been drinking more water or urinating more frequently?
- For cats on chlorambucil: any unusual lethargy, bruising, or bleeding?
- Do you have your reassessment appointment booked to review whether the treatment step is working?
Common IBD follow-up mistakes clinics make
Not establishing the dietary trial as a clinical experiment with a defined endpoint. An elimination diet trial only has interpretable results if it is conducted strictly — 4–6 weeks on the prescribed diet alone, with no other food sources. Owners who “mostly” follow the diet and see partial improvement have produced an ambiguous result. A follow-up call at 2–3 weeks specifically probing dietary compliance — not just asking “how is she doing?” — produces a usable result.
Not checking for hidden dietary cheats. Owners who are committed to the elimination diet frequently overlook flavoured medications, flavoured toothpaste, treats used during training, other pets’ food in a multi-pet household, and outdoor scavenging. A follow-up call that asks specifically about each of these categories catches the “mostly compliant” owner who is inadvertently contaminating a dietary trial.
Not reinforcing medication tapering guidance. Dogs and cats with IBD who respond well to prednisolone need a structured dose tapering plan — typically reducing by 25% every 4–6 weeks once clinical signs are controlled. Owners who taper too quickly relapse; owners who stay on high doses longer than necessary accumulate side effects. A follow-up call that asks “are you on the current dose or have you started to taper?” keeps the tapering schedule on track.
How to automate IBD follow-up without adding to your team’s workload
Nidana Loop schedules a 3-week dietary trial compliance check and a 6–8 week treatment response assessment automatically from the IBD discharge note. The calls ask specifically about dietary compliance, vomiting and diarrhoea frequency, weight, and medication consistency. For patients on chlorambucil, Loop schedules a 6-week haematology reminder. The clinic sees summaries and flags for cases where the owner reports relapse or compliance issues.
