Why Flemish Giants Are Amazing Pets

Impressive Size

Weighing up to 20+ pounds, these rabbits are literally the size of small dogs. Their massive size makes them truly unique and impressive companions.

Gentle Temperament

True to their gentle giant nickname, they are calm, docile, and patient. Even their large size does not prevent them from being wonderful with children.

House Rabbit Friendly

Flemish Giants can be litter box trained and make excellent house rabbits. Many roam freely like dogs or cats, following their owners around.

Affectionate Personalities

Despite their size, they love attention, petting, and even being held when properly supported. They bond deeply with their families.

Care Requirements

What you need to know to keep your Flemish Giant Rabbit healthy and happy

Exercise

Exercise

180 minutes daily

Flemish Giants need several hours of exercise daily in a rabbit-proofed area or secure outdoor run. They should have space to run, hop, and binky. Provide tunnels, cardboard castles, and toys. As house rabbits, they roam freely but still need supervised activity.

Grooming

Grooming

Weekly

Brush weekly using a soft brush or grooming mitt. During shedding seasons (spring and fall), daily brushing helps prevent wool block from ingested fur. Trim nails monthly. Check ears weekly for debris. Spot clean only when necessary and never bathe unless medically required.

Nutrition

Nutrition

Provide unlimited fresh hay (timothy, orchard, or meadow) comprising 80% of diet. Offer 1/4 to 1/2 cup of quality pellets per 5 pounds of body weight daily. Provide 2-4 cups of fresh leafy greens and vegetables daily. Limit treats to small pieces of fruit. Always provide fresh water.
