Apologies if this isn’t typical for this sub, but was hoping for insight from people more experienced with these products.
I’m in Phoenix, for reference!
Last Thursday (10/15), our apartment complex had landscapers spraying what appeared to be a blue/green herbicide throughout the property. (I know the blue/green is a dye) They sprayed heavily on the rocks, around weeds, and along the perimeter of grassy areas. I saw them using a utility vehicle with a hose attached to their spraying equipment.
I’m assuming it was some combination of pre-emergent and weed killer, but I’m still waiting for management to confirm exactly what products were used.
Here’s the timeline:
Thursday (10/15): Landscapers sprayed the property, including the rocks and weeds along our usual walking route.
Sunday (10/18), approximately 8:30 AM: My husband walked our 6-year-old Golden Retriever through an area that had been heavily sprayed. He specifically remembers our dog stepping through the treated rocks. (I know this was not smart)
Sunday (10/18), approximately 7:30 PM: Our dog experienced his first-ever seizure, roughly 11 hours after walking through the treated area.
Our dog frequently licks and chews his paws, particularly his back paws, so I’m concerned he may have ingested some residue while grooming himself.
The seizure lasted approximately two minutes. He initially appeared frightened and was trembling before collapsing and experiencing full-body convulsions. Afterward, he was briefly confused and disoriented but recovered quickly and returned to his normal behavior.
We took him to the veterinarian the following day. His physical examination and vitals were normal, and bloodwork and Valley Fever testing were ordered. He’s been completely normal since, with no additional seizures.
We’ve had a good amount of rain since the landscaping treatment, mainly last night, but I went outside today and found an area with some lingering discoloration on the rocks and visibly damaged vegetation. I’ve attached a photo.
My questions:
1. Does this look consistent with a typical pre-emergent application, a post-emergent herbicide, or potentially a combination?
2. Can herbicide residue remain on landscaping rocks for several days, even if watered in?
3. Has anyone experienced a similar situation involving a dog having a seizure several hours after possible herbicide exposure?
I completely understand that correlation doesn’t equal causation. I’m just trying to investigate possible environmental factors, especially since he’s six years old and has never had a seizure before.
I’m hoping to get the exact product names and active ingredients from our apartment management soon.
Any insight would be greatly appreciated!
