Beyond Antibiotics: How Chikku’s Case Became a Lesson in Better Pet Care

When the same problem keeps coming back, should you look deeper?

Your dog develops a skin problem.

You visit the veterinarian. Medicine helps.

A few days later, the problem returns.

So you go back. Another treatment begins. The symptoms improve again — and then come back once more.

At what point should a pet parent stop asking only, “What medicine comes next?” and start asking, “Do we fully understand what is causing this?”

That question sits at the heart of Chikku’s story.

Chikku is a Pug rescued by New Delhi-based Dr Kumud Sharma, an MBBS doctor with postgraduate training in microbiology. His long skin-health journey eventually involved medicines, laboratory cultures, diet changes and several possible diagnoses.

But the value of his story lies in what other pet parents can learn from it: observe better, communicate clearly with veterinarians, and recognise when a recurring problem deserves a closer look.

Lesson 1: Temporary relief is not always the same as finding the cause

Dr Kumud Sharma first saw Chikku about three years ago at an aquarium shop.

The young Pug had bumps on his head and hair loss across his chest. When Dr Sharma returned a few days later, Chikku looked lethargic and much less active.

The shopkeeper told him the puppy had an “infection” and that no one wanted to take him. Dr Sharma already had a dog at home, but he agreed to take responsibility for the puppy’s treatment.

The family named him Chikku.

His first treatment included antibiotics and antihistamines, and for several days he appeared better. Then the lesions returned. Another course of treatment, including antibiotics and steroids, again brought only temporary improvement.

That pattern is the first lesson: a medicine can reduce symptoms without necessarily explaining why they keep returning.

If the same problem repeatedly returns after treatment ends, tell your veterinarian how quickly it came back, whether it looked the same and how long the previous treatment actually helped.

Lesson 2: Your pet’s history can be as important as a test

Veterinarians see an animal for a limited period; pet parents see them every day. That makes the family an important source of clinical history.

As Chikku’s problem continued, Dr Sharma began tracking details that might otherwise have seemed unrelated: food, treats, weather, medicines, appetite, diarrhoea and bathing.

Over time, those observations became more useful than any single isolated detail.

A simple symptom diary can help: record dates, photographs, food changes, medicines, grooming products, environmental changes and how quickly symptoms improve or return.

Lesson 3: A laboratory result needs clinical context

During Chikku’s treatment, samples were sent to multiple laboratories. Some cultures showed bacterial growth, but interpretations differed over whether that represented infection or normal skin flora.

Dr Sharma’s microbiology background made him look more closely at the sampling process.

In microbiology, how a sample is collected matters. Contamination can influence what grows, and finding bacteria does not automatically prove causation.

With laboratory support, Dr Sharma later arranged controlled sampling from five sites — two affected and three apparently normal. The same growth appeared across all five, and a veterinary colleague suggested it was more likely normal flora than the primary cause.

That experience reinforced a principle Dr Sharma knew well:

Treat the patient, not just the report.

For pet parents, that means understanding that tests are one part of the diagnostic picture. Examination, history, sample quality and treatment response also matter.

Lesson 4: Ask what the medicine is treating

Chikku’s reports also showed resistance to several antibiotics on susceptibility testing. However, the interpretation was complicated by the poor quality of the sample collection. Because the samples were collected in hospital settings, the growth may have been contaminated by hospital-associated microorganisms rather than accurately representing the organisms causing Chikku’s skin condition.

Hospital-associated microorganisms can show greater resistance to antibiotics. If a contaminated or poorly collected sample is treated as a true representation of the patient’s infection, it may lead clinicians towards unnecessary or prolonged antibiotic treatment.

This raised a bigger issue: antibiotics should have a clear clinical purpose, and laboratory results must be interpreted in the right clinical context.

Chikku had been receiving broad-spectrum antibiotics continuously for almost three months. That prolonged exposure affected his normal gut microbiome—the community of microorganisms that supports digestion—and caused diarrhoea. The diarrhoea was therefore not a separate, longstanding gastrointestinal disease; it was a consequence of prolonged antibiotic use.

There is also a wider concern. Unnecessary or irresponsible antibiotic use can encourage the actual disease-causing pathogens to evolve mechanisms that help them survive treatment. This is one way antimicrobial resistance develops. Because the world has a limited reserve of effective antibiotics, protecting their usefulness is important in both veterinary and human medicine.

Antibiotic resistance can also move across the animal–human health boundary. Some bacterial strains that infect animals can also infect people. If those organisms become resistant during veterinary treatment, it may reduce the treatment options available when similar resistant strains affect humans.

Pet parents should never stop prescribed antibiotics on their own.

But they can ask useful questions:

• What infection are we treating?
• What findings suggest that it is bacterial?
• How was the sample collected, and could contamination have affected the result?
• Does the laboratory result fit the pet’s examination and symptoms?
• Should cytology or a properly collected culture be considered?
• What improvement should we expect?
• What happens if the symptoms return after the course ends?

Those are not confrontational questions; they are part of informed pet care.

Veterinary antimicrobial-stewardship guidance supports using antibiotics when there is a reasonable clinical indication and interpreting culture results in context.

The goal is the right antibiotic, for the right problem, when it is actually needed.

Lesson 5: Antibiotic side effects can create a second problem

Diarrhoea during Chikku’s treatment was associated with nearly three continuous months of broad-spectrum antibiotic use. These medicines can disrupt the normal gut microbiome, including microorganisms that help with digestion. This is an important reminder that a new symptom appearing during treatment may sometimes be a side effect of the treatment itself.

Pet parents should report diarrhoea, vomiting, appetite changes or other new symptoms to their veterinarian. They should not stop or alter prescribed medicines without veterinary guidance, but they can ask whether a symptom may be treatment-related and whether the plan needs reassessment.

Lesson 6: When food may be involved, random switching is not enough

Dr Sharma then observed flare-ups after products containing chicken, egg and wheat, while hypoallergenic foods using proteins such as duck or lamb appeared to suit Chikku better.

The family eventually found a routine that worked better for Chikku. But if food allergy is suspected, repeatedly changing foods every few days can make the picture more confusing.

Veterinary dermatology considers a strict elimination diet followed by controlled rechallenge the most reliable way to confirm a food-related reaction; blood, saliva or skin tests alone cannot reliably diagnose food allergy.

So if food appears to be a trigger, discuss a structured diet trial with your veterinarian rather than creating one through guesswork.

Lesson 7: Environment can reveal patterns too

Chikku’s skin improved, but smaller rainy-season flare-ups continued. The family began tracking humidity and moisture, and found that keeping him dry and using a gentle shampoo periodically with veterinary input appeared helpful.

For Chikku, a roughly ten-day bathing routine became part of seasonal management. That is not a universal recommendation; the useful lesson is the pattern.

Pet parents can ask:

Does the problem worsen after rain?

After grooming?

After a new shampoo?

After time outdoors?

After changing floor cleaner?

After a particular treat?

Environmental details that look small at home can become useful information during a veterinary consultation.

Lesson 8: A second opinion is not an insult to your veterinarian

Chikku’s case involved several veterinarians and different interpretations.

Complex dermatological cases do not always produce an immediate answer. Seeking another opinion does not automatically mean the first veterinarian was wrong.

Sometimes another clinician, a veterinary dermatologist or a different diagnostic approach can add useful information. The key is to carry the full history forward.

Bring previous reports, medicine details and photographs, and explain what worked, what did not and for how long.

A second opinion is most useful when the next veterinarian receives the whole story, not just the latest symptom.

The Chikku checklist: what to note when a problem keeps returning

If your pet has a recurring problem, keep these details ready for your veterinarian:

• When did the problem first appear?
• How often does it return?
• What food, treats and supplements is your pet receiving?
• What medicines have been prescribed, and for how long?
• Could any new symptom be a side effect of treatment?
• How quickly did each treatment help?
• How soon did symptoms return?
• Was there itching, fever, diarrhoea, vomiting or appetite change?
• Does the condition appear seasonal?
• Were there new shampoos, cleaners, bedding or environmental exposures?
• What tests have already been performed?
• How and where were samples collected?
• Were samples collected before antimicrobial treatment?
• Could contamination have affected the laboratory result?
• Has your veterinarian discussed alternative causes or referral?

This record does not diagnose the pet; it gives the veterinary team better information to work with.

Chikku today — and the lesson Dr Sharma wants pet parents to remember

Today, Dr Sharma describes Chikku as healthy, energetic and “way too playful”. The antibiotic-associated diarrhoea has settled, and his skin is being managed through diet, environmental care, observation and veterinary guidance.

That is very different from the lethargic puppy Dr Sharma first saw three years ago.

Through this collaboration with Pets News Network, Dr Sharma hopes Chikku’s experience encourages pet parents to become more attentive partners in their animals’ healthcare.

That does not mean diagnosing pets at home or stopping medication without veterinary advice. It means documenting, observing, asking clear questions and helping the veterinary team see the entire pattern rather than only the latest flare.

Chikku cannot explain that one food seems to worsen his skin, that humid weather affects him, or how long the last medicine helped. That part belongs to the people caring for him.

Pet parents do not need to become veterinarians. But they can become better observers — and sometimes the smallest detail noticed at home helps the veterinarian see the bigger picture.

That may be Chikku’s most important lesson: when your pet cannot tell you what is wrong, your attention becomes part of the care.
