While Australians have an obsession with eating avocado, it should never be shared with our furry friends. Avocado is bad for dogs to eat because it contains a substance called persin, which can be toxic to dogs in large quantities. Persin is a fungicidal toxin that is found in the leaves, bark, and fruit of the avocado plant. While persin is generally harmless to humans, dogs are more sensitive to its effects and can experience symptoms such as vomiting, diarrhea, and difficulty breathing if they consume too much avocado. Additionally, the high fat content in avocado can cause stomach upset and even pancreatitis in dogs, especially if they consume large amounts. Therefore, it's best to avoid feeding avocado to dogs as a precautionary measure.


Dairy products

 Dairy foods can be bad for dogs to eat because many dogs are lactose intolerant, which means they lack the enzyme lactase that is needed to break down lactose, the sugar found in milk and other dairy products. Without lactase, dogs cannot properly digest lactose, which can lead to gastrointestinal symptoms such as diarrhea, bloating, and gas. While some dogs may be able to tolerate small amounts of dairy products, it's generally best to avoid feeding them to dogs altogether, especially if your dog has a known sensitivity or allergy to dairy. Additionally, some dairy products, such as cheese and butter, can be high in fat, which can lead to obesity and other health problems if consumed in excess. Therefore, it's important to always provide your dog with a well-balanced diet that is specifically formulated for their nutritional needs. 

Cooked bones 

feeding your dog cooked bones of any type can be fatal. The composition of bones changes during the cooking process, and cooked bones become brittle and can splinter. If your dog eats cooked bones there is a high risk of bone becoming caught in the digestive tract or splintering and causing damage.

Macadamia nuts are one of the most dangerous types of nuts for dogs to eat, as they can cause symptoms such as lethargy, vomiting, hyperthermia, and tremors.

Other types of nuts, such as almonds, pecans, and walnuts, can also cause gastrointestinal upset, such as vomiting and diarrhea, especially if they are salted or coated in other flavors. Additionally, nuts are high in fat, which can cause pancreatitis in dogs if consumed in large quantities.
