Why would I need to use a dog weight chart?

If your dog has eaten a potentially poisonous substance such as chocolate or xylitol our advice is simple. Get in touch with your vet straight away or, out of hours, contact your nearest Vets Now pet emergency clinic or Vets Now 24/7 hospital.

One of the questions your vet may ask is whether you know how heavy your dog is. This is because smaller breeds are far more likely to fall seriously ill after eating a small amount of something toxic than larger dogs.

One of the ingredients in chocolate, theobromine, is poisonous to dogs.

Doses in the region of 100-150 milligrams per kilogram of bodyweight are highly dangerous so if you have a Labrador weighing 30kg, as little as 3g of theobromine could be fatal. You’ll find that amount in one 500g bar of dark chocolate. However, for West Highland Terriers weighing just 10kg a 175g bar of dark chocolate could prove deadly.

Use the dog weight chart at the bottom of this page to find the ideal weight range of each breed.
