Background: Clara Juniper Hayes is a 38-year-old herbalist and small business owner based in Asheville, North Carolina, a hub for natural living and holistic wellness. Born and raised in the Pacific Northwest, Clara grew up surrounded by lush forests and developed a deep love for plants and animals from a young age. Her grandmother, a folk herbalist, taught her the basics of foraging and crafting remedies, which sparked her lifelong passion for natural healing.
Profession: Clara is the founder of Herb and Fur, a blog and online shop dedicated to sharing knowledge about herbal remedies, sustainable living, and holistic pet care. She’s a certified herbalist with a degree in ethnobotany from the University of Oregon and has spent over a decade studying the medicinal properties of plants.
Personality: Warm, approachable, and a bit quirky, Clara is known for her down-to-earth writing style and knack for making complex herbal knowledge accessible. She’s an avid hiker, often accompanied by her rescue dog, Sage, and believes in the healing power of nature for both humans and their furry companions. She’s passionate about eco-conscious living and sources all her products ethically.
Hobbies: Foraging for wild herbs, tending her backyard apothecary garden, knitting pet sweaters, and hosting community workshops on herbal medicine. She’s also a self-proclaimed “tea nerd” who experiments with blending her own herbal infusions.
Why She Started Herb and Fur: After years of working in corporate wellness and feeling disconnected from her roots, Clara launched Herb and Fur to share her love for natural remedies and pet care. She wanted to create a space where people could learn to use plants to support their health and their pets’ well-being, all while fostering a deeper connection to the earth.
Fun Fact: Clara once spent a summer living off-grid in a tiny cabin in the Blue Ridge Mountains, where she perfected her recipe for a lavender-chamomile calming salve for anxious dogs.
Key Takeaways
- Onions, garlic, leeks, chives, and shallots are all part of the allium family and are toxic to both dogs and cats.
- The toxin damages red blood cells, which can lead to anemia days after exposure rather than immediately.
- Cats are generally more sensitive to allium toxicity than dogs, and powdered or cooked forms are just as dangerous as raw.
Onions don’t get talked about as much as chocolate or grapes, but they belong in the same conversation. Onions and their relatives in the allium family are toxic to both dogs and cats, and the effects can sneak up days after exposure.
Which Foods Count as Allium?
- Onions (all colors and forms, including cooked, raw, and powdered)
- Garlic
- Leeks
- Chives
- Shallots
This means onion soup, garlic bread, seasoned broths, and many pre-made sauces are all potential hazards, not just raw onion slices. Powdered and dehydrated forms, like onion powder or garlic powder in seasoning blends, are actually more concentrated than the fresh vegetable.
How Allium Toxicity Works
Compounds in the allium family break down red blood cells, leading to a condition called hemolytic anemia. Unlike grape toxicity, which can cause rapid kidney injury, allium toxicity tends to build up over several days as red blood cells are progressively destroyed, which is why symptoms are sometimes delayed and easy to miss at first.
Symptoms of Onion or Garlic Poisoning
- Lethargy and weakness
- Pale or yellowish gums
- Reddish urine
- Rapid breathing or heart rate
- Vomiting or diarrhea
- Reduced appetite
Symptoms may not appear for several days after exposure, especially with smaller, repeated amounts (like table scraps seasoned with onion or garlic over time).
Are Cats More Sensitive Than Dogs?
Yes. Cats are generally considered more sensitive to allium toxicity than dogs, and it takes a smaller relative amount to cause harm. This is worth keeping in mind if your household has both dogs and cats sharing scraps.
What to Do If Your Pet Eats Onion or Garlic
- Contact your veterinarian, especially if a meaningful amount was eaten (a bite of seasoned food is different from a whole cooked onion).
- Watch closely for the delayed symptoms above over the following several days.
- Bring any packaging or ingredient information to your vet visit.

Frequently Asked Questions
Is a small amount of onion dangerous for dogs?
Small, occasional amounts (like a bite of seasoned food) are less likely to cause serious harm than a large or repeated exposure, but there’s no fully ‘safe’ amount, and effects can be cumulative over time.
Are cats or dogs more sensitive to onion toxicity?
Cats are generally considered more sensitive to allium toxicity than dogs, so extra caution is warranted for households with cats.
How long after eating onions do symptoms appear?
Symptoms of hemolytic anemia can take several days to become apparent, which is different from the faster-acting toxins in grapes or chocolate.
