Grapes, Raisins, Sultanas and Currants

How dangerous are grapes and raisins to dogs?

It only takes a very small amount of grapes, raisins, sultanas or currants to cause severe issues in some dogs and can even result in death. There is no correlation between the amount of fruit eaten and the size of dog and research has not yet revealed which part of the grape or raisin is toxic to our dogs. Vitis Vinifera is the chemical found within grapes and raisins that can cause serious damage to their kidneys.

Whilst one dog may have eaten a handful and been fine, it may only take eating a single raisin to prove fatal in another dog.  For this reason, it’s not advisable to feed any grapes, raisins, sultanas or currants to your dog.  Be aware of any products such as fruitcakes, muffins or mince pies containing these fruits and to store foods containing these ingredients well out of reach of your dog.

If you’re baking at home with these potentially toxic ingredients be extra careful and do not leave children alone with your dogs in the kitchen or the food cupboard within reach of your potentially greedy dog.

Chocolate and cocoa products are poisonous to dogs and in large enough amounts can sadly be fatal. The toxic component of chocolate is theobromine as chocolate comes from the Theobroma cacao tree.

We can easily metabolise theobromine but it is not the same for our dogs. They metabolise theobromine much more slowly, causing it to build up to toxic levels in their system.

How much chocolate is poisonous to a dog?

The level of toxicity of chocolate to your dog depends on the type of chocolate e.g white, milk, dark chocolate, the amount consumed and your dog’s size. In general a larger dog could consume more chocolate than a small dog before suffering ill effects. Cocoa powder is particularly concentrated and if your dog has licked it, book an emergency visit with your vet.

What are the symptoms if my dog eats chocolate or licks cocoa powder?

Initially, chocolate poisoning will usually present with severe hyperactivity.

So if you suspect your dog has eaten chocolate and they are hyperactive, panting excessively and unable to settle please call your vet. In extreme cases large amounts of theobromine can produce muscle tremors, seizures, an irregular heartbeats, internal bleeding, organ damage or a heart attack.

What is carob and is it safe for dogs?

Carob, also known as St. John’s bread, is a sweet and nutty-flavoured pod that and grows on trees is often used as a substitute for chocolate. It is a popular and natural alternative to chocolate for your dog as it is a sweet and dogs enjoy its taste and texture. Unlike chocolate, carob is safe for dogs to consume as it contains no theobromine.

It is packed with essential vitamins and minerals that contribute to your dog's overall health. Carob is low in fat and is also a good source of calcium, magnesium, and phosphorus, which are important for strong bones and teeth. Furthermore, carob is loaded with antioxidants, promoting a healthy immune system for your dog. It is used in our Solo Vegetal dry food which is what makes Solo Vegetal so delicious!

Onions, Chives and Leeks

Onions, chives and leeks (Allium species):

We all love to cook with onion for ourselves (especially being plant-based), but when onions are ingested in sufficient amounts by our pets the chemicals in these foods have the ability to destroy their red blood cells causing severe anaemia due to the breakdown of red blood cells.

Eating onions of more than 0.5% of your dog’s body weight are potentially toxic. Cats and some Japanese breeds of dog such as the Akita are more sensitive to the toxic effects than most. Symptoms are generally secondary to the anaemia and include weakness, lethargy and pale coloured gums.

Signs and Symptoms:

Your dog may have an onion smell on its breath, be lethargic, have pale gums (due to the anaemia), and pant excessively. Book an appointment with your vet if you notice and smell these signs and stop your dog from eating these foods or raiding waste and recycling bins.

What about potato skins?
Always peel potatoes before cooking and feeding to your dog. The potato skin contains high levels of solanine that is toxic to our pets, so always just peel those potatoes.

Xylitol

Xylitol is an artificial sweetener (not great for us either as humans!) It is often found in sweets, chewing gums, some nut butters and even toothpastes.

It is important to keep these products out of reach of your dogs or buy natural products with no additives – especially peanut butter. Xylitol is poisonous to dogs. Levels of toxicity are potentially mild to severe but depend on the amount ingested.

It is important to be aware that signs of Xylitol poisoning vary and can present rapidly or be delayed.

Common signs to watch out for are:

  • Weakness
  • Lethargy
  • Collapse
  • Vomitting
  • Tremors
  • Seizures
  • Jaundice (yellow skin or eyes)

There is the story of prisoners in a UK jail who had their friends bring in large quantities of chewing gum with Xylitol in it which they fed to the guard dogs and caused some deaths!

Can dogs be fed garlic?
Can dogs be fed garlic?
Yes they can be fed garlic! As mentioned above; onions, leeks and chives contain a large number of thiosulphates. These can cause anaemia in dogs if eaten, but the amount of thiosulphate in garlic is very low. The risk of them developing anaemia from eating one clove of garlic is negligible.
Garlic has so many beneficial effects in our dogs and can definitely be fed to our dogs, in moderation.
Prof Andrew Knight mentions this in his research on his sustainable pets page looking at the health status of vegan dogs:
"Dogs eating nutritional yeast and/or garlic did seem to fare somewhat better than the rest of the dogs. 81.6% (102/125) of the dogs eating nutritional yeast were in good to excellent health, compared to 72.6% of those who did not. 83.3% (70/84) of dogs eating garlic were in good to excellent health, compared to 80% of those who did not. Dogs eating either nutritional yeast or garlic also had a much higher incidence of good or improved coats—44% for nutritional yeast eaters and 47.6% for garlic eaters, compared to only 22.9% of dogs not eating nutritional yeast and 17.8% of dogs not eating garlic.”

Can dogs be fed nuts?
Yes, we have a misconception that as a nut allergy is common in humans, that it will be the same for our dogs, but this does not seem to be the case. Nuts are an excellent source of protein, calcium, fibre and healthy fats in your dog’s diet. The best is to use ground almonds or chopped/crushed cashews and brazil nuts in recipes to make it digestible for your dog. (see our delicious delicious wholefood recipe FEED THE RAINBOW here)

Give peanut butter on "licki mats" or in our recipes to mix with the supplement. Ensure that it is pure peanut butter with no added palm oil, sugar, salt or sweeteners such as xylitol.

The nuts NOT to feed are macadamias. The toxic mechanism is unknown but it can affect nerve and muscle function. There is not enough known about pistachios in our dogs so I would not feed those (especially the hard shells of pistachios that could get stuck in their intestine).

Can dogs be fed avocadoes?
Dog eating avocado
Avocados can be fed to our dogs in small quantities. The concern is a chemical called persin which in large quantities can be toxic to most animals including dogs. In large amounts, it can cause vomiting and diarrhoea though in small enough amounts, persin shouldn’t cause any problems.
(Read this article about the potential use of avocado in dog food!)
Persin is mainly found in the skin and stalk of the fruit (which we are unlikely to feed to our dogs).
We all know NOT to give them the pip or stone of the avocado as it can cause blockages. Like everything, just keep it in moderation. Too much of any high fat food (avocado contains saturated fat) can result in a very painful condition called pancreatitis - something we wouldn’t wish on any of our dogs!

Is popcorn a good vegan treat to give to our dogs?

Popcorn being fed to a dog - we don't recommend it!

Read here all about the importance of dental health in our dogs and why we shouldn't feed our dogs popcorn as the husks will get stuck in their gumline and can cause gum damage!!
