Help with Caterpillar Identify.. Brown Tail Moth Catterpillar?
Hi All,
I was wondering if anyone can help us identify the Caterpillar we found in the garden yesterday?
Our small dog was quite unwell for 2 weeks prior to finding this and we found what we think was a digested caterpillar in her stool at the start of her being unwell.
To me it looks like a Brown Tail Moth Caterpillar? I know these are quite toxic to dogs too...
If it is, I'm concerned where they might be. It's only a small garden with a few potted plants/trees.

Many thanks.

Could be Knot Grass moth, does say often confused with BT moth
Eight out of ten owners who expressed a preference said their cats preferred other peoples gardens1 -
100% Knotgrass.1

Legends! Thank you. Not sure why that one didn't come up when I was trying to identify. Makes more sense, we do have some heather planted... maybe they are living in there....
Any suggestions on how to deal with as our dog was very poorly?0 -
Not something I've come across before, but looks like knotgrass caterpillars are poisonous to dogs because they carry the toxins from their primary food source, being knotweed plants. Including the dreaded Japanese knotweed.
Advice is to keep dogs away from any knotweed plants - which begs the awful question, do you have Japanese knotweed in or near your garden?1 -

Thanks for this.
Our 10 year old small dog (3kg) definitely had digestive issues. You could hear her belly from about 5 meters away. She had breathing issues, rash, lethargic etc.
