FEEDING dogs chocolate could have fatal consequences this Easter, a leading veterinary charity has warned pet owners across York and North Yorkshire.

According to the PDSA, large amounts of chocolate can poison dogs and other pets, including hamsters and rats, due to the toxic effects of theobromine, a component of chocolate.

The effects of chocolate poisoning in dogs usually appear within four to 24 hours of ingestion, and the effects can last as long as 72 hours.

Symptoms include vomiting, abdominal tenderness, hyperactivity, salivation and increased heart rate. In severe cases there are fits, increased rate of breathing and heart beat irregularities.

"Easter and chocolate go hand-in-hand, but where pets are concerned people should avoid feeding it to them at all costs," said PDSA senior veterinary surgeon Elaine Pendlebury.

"Not only is there the issue of chocolate toxicity for dogs and many other pets, but it is also worth bearing in mind that the high sugar content of chocolate won't do anything for your pet's waistline or teeth either."
