How to Fatten Up My French Bulldog Puppy

If your French Bulldog puppy seems underweight, you may worry about their growth and health. Supporting appropriate weight gain in Frenchies requires understanding key considerations around diet, nutrition, activity levels, and veterinary guidance. Use these tips to safely fatten up your French Bulldog puppy.

How to Fatten Up My French Bulldog Puppy

The first step involves confirming if your puppy does in fact need supplemental weight gain support. Here are some ways to analyze their status:

Track Growth Rate

Weigh puppies at least weekly on a home pet scale to chart weight fluctuations. Healthy increases average 2-3 pounds per month during the crucial 4-12 month puppy growth phase.

Note Body Condition

Visually and by touch assess if ribs or spine show prominently indicating thinness versus healthy layering. Muscle tone should develop but not appear emaciated.

Compare to Breed Standards

Adult Frenchies range 18-28 pounds when physically mature. Ensure your pup stays proportionate to size norms throughout juvenille development.

Veterinary Guidance

Your veterinarian provides the best body condition score and growth benchmarking via routine well visits. Bring concerns to them if your Frenchie pup drops percentiles or differs from littermates.

Frenchie Puppy Age Average Weight Range
8 weeks 2-4 pounds
16 weeks (~4 months) 8-14 pounds
6 months 13-19 pounds
9 months 16-25 pounds (filling out)


If your puppy falls under these averages consistently, boosting their weight through diet may help alignment.

Adjusting Your French Bulldog Puppy’s Diet

If your veterinarian green lights targeted weight gain support, gradually transition your Frenchie puppy to a higher calorie puppy kibble or add nutrient rich mix-ins to their existing food.

Higher Calorie Kibble

Switch dry kibble to a brand formulated specifically for puppies, which provides 30% more calories than adult dog foods. Stick to reputable company lines meeting WSAVA guidelines.

Wet Food Mix-Ins

Introduce nutritionally balanced canned wet foods. The soft texture and meaty smells gets picky pups eating more. High protein, grain free options work well.

Healthy Toppers

Boost dry kibble acceptance through irresistible yet healthy mix-ins like shredded chicken, lean ground beef or turkey, chopped hard boiled eggs, unsweetened yogurt, peas, carrots or green beans. Introduce one new additive at a time.

Feeding Schedule Changes

Instead of one large meal, break daily intake into 3-4 smaller portions which may stimulate appetite better for frequent nibblers. Always maintain consistent feeding times.

Monitor if weight and body condition show improvement after 4 weeks adjusting food format, volume, or calorie increase. Discuss medicated supplements if excess dieting requires an underlying health issue intervention.

Method What to Do
Higher Calorie Kibble Transition gradually to 30% higher calorie puppy formula dry food
Wet Food Mix-Ins Introduce nutritionally balanced canned wet foods into kibble
Healthy Toppers Boost acceptance through irresistible yet healthy add-ins
More Small Meals Break daily intake from one large into 3-4 smaller feedings


Adjust your French Bulldog’s puppy diet format using these strategies for potentially improving weight gain.

Other Ways to Fatten Up a French Bulldog Puppy

Beyond just dietary changes alone, applying additional tactics may help tip scales towards a healthy weight increase:

Parasite Prevention/Treatment

Get fecal tests done to rule out intestinal parasites stealing nutrients. Tackle any presence immediately through veterinary prescribed medications.

Exercise Regulation

Avoid strenuous or high impact exercise that burns more calories than taking in. Focus on shorter, positive training sessions and gentle play until filled out.

Appetite Stimulants

Discuss non-habit forming supplement options with your vet if lack of food motivation concerns the root issue stalling weight gain.

Stress Reduction

Anxiety causes many health ripple effects including weight fluctuations and poor food drive. Try anti-stress supplements, pheromone diffusers, rewarding alone time in safe spaces, and maintaining consistent comforting routines.

Do not attempt any extreme “shortcuts” claiming rapid results like high fat diets, forced overfeeding, or use of medications without direct veterinary supervision. Patience and balance proves vital.

When to Worry About Underweight French Bulldog Puppies

While supporting your French Bulldog’s weight gain journey, also remain alert regarding these situations signaling potential serious underlying conditions requiring urgent veterinary diagnoses beyond basic dietary tweaks alone:

Failure to Gain After Month+ Efforts

If an underconditioned puppy continues losing weight or shows no improvement even after 30 days adjusting food format, volume, calories and environment, seek medical exams.

Significant Loss in Short Period

Rapid weight decrease risks malnutrition or disease. Schedule urgent veterinary bloodwork and treatment if your Frenchie pup sheds 2+ pounds quickly without diet change.

Poor Food Motivation

While finicky appetites happen, complete disinterest in all foods plus weight loss points to chronic health issues necessitating interventions like appetite stimulant medication.

Additional Symptoms

Watch for lethargy, vomiting, diarrhea, enlarged abdomen or breathing issues coupled with skinniness pointing to infections, blockages, parasites or organ impairment needing diagnosis.

Stay vigilant regarding weight fluctuations in young French Bulldogs up to one year old. Always contact your trusted veterinarian promptly if conservative efforts fail improvement after 4 or more weeks.
