Overview

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.

💊 Omega3s

Tub Joint Supplement

Omega-3s offer many benefits for dogs, especially Great Danes. Because Danes are prone to growth and joint issues, a quality fish oil supplement can help support joint health. Omega-3s also provide anti-inflammatory support and can benefit the skin, coat, kidneys, and heart. I always knew Omega-3s were helpful, but the more I’ve learned, the more surprised I am that more dog owners don’t include them in their diets.
The real question is why isn’t everyone adding Omega-3s to their dogs diet? Since I’ve been researching all of this I am finding more ways to increase the health of my dogs. I have noticed a difference in their coats within a couple of weeks.

  • Joint benefits (crucial for Great Danes)
  • Helps dry skin which every dog needs help with
  • Increase brain function (something I need)
  • Healthier coat benefits
  • Even cardiovascular benefits

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
