Milk and other dairy products

Potato, rhubarb, and tomato leaves; potato and tomato stems

Contain oxalates, which can affect the digestive, nervous, and urinary systems. This is more of a problem in livestock.

Raw eggs

Contain an enzyme called avidin, which decreases the absorption of biotin (a B vitamin). This can lead to skin and hair coat problems. Raw eggs may also contain Salmonella.

Raw fish

Can result in a thiamine (a B vitamin) deficiency leading to loss of appetite, seizures, and in severe cases, death. More common if raw fish is fed regularly.

Excessive salt

If eaten in large quantities it may lead to electrolyte imbalances.

Sugary foods

Can lead to obesity, dental problems, and possibly diabetes mellitus.

Table scraps (in large amounts)

Table scraps are not nutritionally balanced and if excessively fed can lead to obesity. Fat should be trimmed from meat; bones should not be fed.

Quick Tip

Microchipping your dog is advisable, a small device is simply placed under the skin containing a unique number. This number is stored on a national database with the owner’s contact details so if a dog is ever lost the owner can be notified.
