Every so often a case comes into work that prompts me to write a blog post about it. This time I decided to write about poisonous things that you may or may not know are poisonous, either in your house or when you're out walking the dog.
I used the BSAVA/VPIS Guide to Common Canine and Feline Poisons to help me. It was put together by the
BSAVA and the
VPIS to aid Veterinary practices. We can contact the VPIS at any time for advice on a case but they decided to put this book together using their most common cases.
Obviously, this list is very limited. There are a great many poisonous things out there, and I've chosen to only list a few drugs but, generally speaking, if you're pet eats any of your medication you should contact your Vet as soon as possible. Not every medication is bad but most of them can lead to problems, especially if ingested in excess.
I've also not listed any actual poisons, for example slug and rat bait, weed and plant killer. I felt those were kind of obvious but in case they're not ...... THEY'RE POISONOUS! If your pet ingests any of them or gets them on their coat, contact your Vet as soon as possible.
Another one I've not listed but is common, especially in the winter, is Ethylene Glycol (Antifreeze), it is sweet tasting so pets want to lick it and it is EXTREMELY toxic to them.
As I said, this list is limited, I've tried to keep it to common and/or household toxins. I'll be listing the onset times of clinical signs as well as what the clinical signs are. In those lists there may be some words you don't know, I have made a list at the end of any words I think readers may have trouble with. If there's a word you don't know and I haven't listed it at the end, let me know in the comments.
So on with the list, to keep it simple I'll be using the alphabet as my guide.

Onset of clinical signs within 1-2 hours
Common signs are
Other signs are

Theobromine is the name of the toxic part of chocolate. The darker the chocolate the more Theobromine per gram. Dogs are also at risk from the use of cocoa shells instead of, for example, bark in gardens.
Onset of clinical signs usually within 4 hours, sometimes up to 24 hours
Common signs are
Other signs are
Muscle rigidity
Tremors
Convulsions
Tachypnoea

Lily toxicity in cats
The pollen of the lily is the usual source of ingestion. If the pollen gets on the fur, the cat will then groom it off and ingest it but there is also a risk if the cat eats the petals.

Cats with pre-existing renal impairment are at higher risk
Common signs are
Vomiting

Onion toxicity in dogs
Baby food has quite a high concentration of onions. I mention this because a lot of dog owners may use baby food to hide crushed tablets in.
