Prevent further access.

Prevent your dog from eating any further onion or onion products. It is important to limit the amount eaten as much as possible. If your dog has had processed food with onion in, it is worth making sure there are no other sources in any other foods. Clean up any spills on the floor or accessible products on surfaces and shut your dog away while you do this.

Get the details.

Work out how much onion your dog had eaten and take a note of when it happened. It is important to try and work out roughly how much onion product your pet has eaten, so the veterinarian can use this with your pet’s body weight to calculate whether this is likely to be a toxic dose or not. It is also useful to try and figure out when the onion was eaten, as this will help the veterinarian plan the right treatment for your dog.

Call your veterinarian.

In all cases, it is essential to seek the advice of your veterinarian, even if it’s just a phone call to discuss the situation! Provide the veterinarian with the information you have gathered- they will be able to help formulate a plan of action. If your usual veterinarian is not available, an emergency clinic or the nearest open veterinarian will be able to provide you with the correct advice.

Follow your veterinarian’s instructions.

The veterinarian may recommend seeing and examining your dog at the clinic, and the sooner this happens, the better your chances of a successful outcome. If the amount eaten is not a toxic dose, the veterinarian may be happy for you to monitor your dog at home, but it is best to seek advice first in any case.

Don’t treat at home.

It is important not to try and treat these problems at home. It is easy to cause more harm than good with a home remedy- many are unproven or even dangerous. Any delay using inappropriate or ineffective remedies may mean that a treatable problem is left too long, and it may be too late if you later decide to seek professional help.
