What Can Jack Russells Not Eat?

What can Jack Russells not eat?


Jack Russell Terriers are known for their boundless energy, spirited personalities, and inquisitive nature. These small dogs make wonderful companions, but when it comes to their dietary habits, there are some foods that you should absolutely avoid. Just like with any dog breed, it’s crucial to understand what can Jack Russells not eat? In this article, we will explore the foods and substances that can be harmful or even fatal to Jack Russells.

  1. Chocolate and Caffeine

One of the most well-known foods that dogs, including Jack Russells, should never consume is chocolate. Chocolate contains theobromine and caffeine, both of which can be toxic to dogs. Jack Russells are particularly susceptible due to their small size. Theobromine can affect a dog’s heart, central nervous system, and kidneys, leading to symptoms such as restlessness, increased heart rate, vomiting, diarrhea, seizures, and, in severe cases, death. Dark chocolate and cocoa powder have higher theobromine content, making them even more dangerous. Keep all chocolate and caffeinated products well out of reach of your Jack Russell to prevent accidental ingestion.

  1. Grapes and Raisins

Grapes and raisins are another group of foods that should never be given to your Jack Russell. While the exact toxin in grapes and raisins is still unidentified, they are known to cause kidney failure in dogs, and the reaction can vary from dog to dog. Some dogs can eat grapes without issues, while others may become seriously ill or even die from a relatively small amount. It’s best to avoid this fruit altogether to ensure your dog’s safety.

  1. Onions and Garlic

Onions and garlic are part of the Allium family, and they contain compounds that can be toxic to dogs when consumed in sufficient quantities. These compounds can damage a dog’s red blood cells, leading to a condition called hemolytic anemia. Symptoms may include weakness, vomiting, diarrhea, and difficulty breathing. Jack Russells are small dogs, so even small amounts of onions and garlic can be dangerous. It’s important to avoid feeding them foods that contain these ingredients, including garlic bread, onion rings, and dishes prepared with garlic or onion seasoning.

  1. Xylitol

Xylitol is an artificial sweetener commonly found in sugar-free gum, candies, baked goods, and some toothpaste. It’s highly toxic to dogs, including Jack Russells, and can lead to rapid insulin release, causing a severe drop in blood sugar (hypoglycemia). Xylitol can also damage a dog’s liver. Symptoms of xylitol poisoning may include vomiting, loss of coordination, seizures, and even death. If you suspect your Jack Russell has ingested anything containing xylitol, seek immediate veterinary assistance.

  1. Alcohol

Alcohol is absolutely off-limits for dogs, including Jack Russells. Even small amounts of alcohol can cause alcohol poisoning in dogs, leading to symptoms like vomiting, diarrhea, coordination problems, breathing difficulties, and, in extreme cases, coma and death. Dogs should never be allowed to consume alcoholic beverages or foods cooked with alcohol. It’s essential to keep these substances away from your furry friend at all times.

  1. Bones

While it’s common to see dogs chewing on bones in cartoons and movies, in reality, feeding dogs cooked bones is a risky practice. Cooked bones can splinter and cause intestinal obstructions or perforations, which can be life-threatening. Instead, if you want to give your Jack Russell a bone, choose raw, uncooked bones specifically designed for dogs, such as raw beef bones or rawhide chews. Supervise your dog while they enjoy their bone to ensure their safety.

  1. Fatty and Spicy Foods

High-fat and spicy foods should be avoided for Jack Russells and many other dog breeds. Fatty foods can lead to pancreatitis, a painful and potentially life-threatening condition characterized by inflammation of the pancreas. Symptoms of pancreatitis in dogs may include vomiting, diarrhea, loss of appetite, and abdominal pain. Spicy foods, on the other hand, can irritate your dog’s digestive system and lead to gastrointestinal upset. Stick to a balanced and appropriate dog food diet to keep your Jack Russell in good health.


As a responsible Jack Russell owner, it’s essential to be aware of the foods and substances that can harm your beloved pet. Understanding “What can Jack Russells not eat?” is a vital step in keeping them safe, healthy, and happy. Be vigilant about keeping dangerous foods and substances out of your dog’s reach, and always consult your veterinarian if you suspect your Jack Russell has ingested something harmful. By taking these precautions, you can provide a long and fulfilling life for your Jack Russell Terrier.
