Dogs don’t come with warning labels, so prevention really is everything. For Great Danes (and other big breeds who think their stomach is a trampoline), staying ahead of medical issues isn’t optional – it’s survival. This guide covers the essentials: core preventatives, supplements, medications, and how each one helps keep your dog stable, safer, and out of the emergency vet as much as possible.
Always work with your own veterinarian. Doses, products, and timing should be personalized for your dog.
Core Preventatives Every Great Dane Needs
❤️ Heartworm Prevention
Heartworm is spread by mosquitoes. Monthly preventatives are far easier — and safer — than treating infection.
- Prevents heartworm disease
- Often covers intestinal parasites
- Monthly dosing (chew/tablet/topical)
🪳 Flea & Tick Prevention
Fleas make everyone miserable. Ticks can transmit serious infections. Work with your vet for local risk.
- Stops infestations early
- Helps prevent tick-borne disease
- Reduces itching and irritation
💉 Vaccinations
Your vet sets the schedule based on age, lifestyle, and local disease risk.
- Rabies
- DHPP (distemper/parvo/etc.)
- Leptospirosis (where recommended)
- Bordetella/Influenza for social dogs
Vaccines prevent contagious diseases that can permanently damage organs or be rapidly fatal.
🪱 Dewormers
Intestinal parasites are common. Dogs pick them up from soil, wildlife, puddles — and bad decisions.
Common active ingredients include:
- Fenbendazole
- Pyrantel
- Praziquantel
- Combination products

Under Construction →Preventatives Specifically Helpful for Great Danes
🦴 Joint Supplements
Giant-breed dogs often benefit from joint support long before they look “old.”
- Glucosamine & chondroitin
- MSM
- Omega-3 fatty acids (fish oil)
These don’t rebuild damaged joints, but they can improve comfort and mobility over time.
🧫 Probiotics & Digestive Support
A stable gut supports digestion, the immune system, and helps reduce stomach upsets.
- Veterinary-formulated probiotics
- Digestive enzymes (when recommended)
- Whole-food supplements for sensitive stomachs
⚠️ Pre-Bloat Habits (GDV Prevention)
No medication completely prevents bloat, but smart habits help minimize risk in Great Danes.
- Smaller, spaced meals
- Slow-feeder bowls for vacuum eaters
- No heavy exercise right before/after meals
- Moderate water intake around feeding
- Reduce stress/anxiety
- Know GDV emergency signs
Medications You May Use Under a Vet’s Direction
💊 Anti-Inflammatories (NSAIDs)
Used for joint pain, injuries, or post-surgery soreness. Only use dog-safe NSAIDs prescribed/approved by your vet.
Never give human meds like ibuprofen/naproxen/Tylenol unless explicitly directed by your vet.
🌼 Allergy Medications
Allergies can show up as itchy skin, ear infections, licking paws, or GI upset. Your vet may suggest:
- Antihistamines (vet-approved dosing)
- Apoquel or Cytopoint injections
- Prescription shampoos/ear meds
🩺 Antacids / GI Protectants
For reflux, sensitive stomachs, or certain bloat concerns, vets may recommend omeprazole, famotidine, or sucralfate.
Use only under veterinary direction and correct weight-based dosing.
When To Use What
- ✅ If the problem is parasites, focus on preventatives (heartworm, flea/tick, deworming).
- ✅ If the problem is structural (joints, growth, breed risk), consider supplements, weight management, and vet-directed meds.
- ✅ If the problem is behavioral/environmental, address training, enrichment, and stress reduction before adding meds.
When in doubt, call your vet and describe exactly what you’re seeing. It’s always better to ask than to guess.
🩹 Prophylactic Gastropexy
A prophylactic gastropexy is a preventive surgery where the stomach is anchored to the abdominal wall to help prevent twisting during a bloat (GDV) event. While it does not stop gas buildup, it dramatically reduces the risk of fatal gastric torsion.
What it helps prevent
- Stomach twisting (torsion)
- Life-threatening GDV episodes
- Emergency surgery in the middle of the night
What it does not prevent
- Simple “gas bloat” / distension
- The need for careful feeding/exercise habits
- Other abdominal emergencies unrelated to GDV
