This is a weird one. I have a foster dog, Scarlett Jo. Scarlett is 2-3 old, spayed, on heartworm preventative. She appears to be a catahoula mix. Normally, Scarlett stays in a dog run in the back yard, weather permitting. If the weather’s bad, I’ll put her in the run to potty, then bring her back in the house. However, on a few occasions I’ve walked her on a leash in the evening.
The first time she had a seizure, I was walking her on leash, she was running along, sniffing the ground. She acted like she was grabbing something on the ground, the she started violently shaking her head, foaming at the mouth and backing up rapidly. She came out of it after a few seconds. It was dark so I thought maybe she’d grabbed a toad. She was fine afterward so I gave it no thought. A month or so later, took her out in the front yard, same thing, only a more prolonged seizure complete with paddling, eyes rolled back in her head and loss of bowel and bladder control. She recovered quickly and was fine. Last night it was cold and rainy. Took her out to potty and bam, she had a major seizure just as soon as she was out in the yard.
This only happens in the front yard. I’ve walked her in the backyard with no issues. I thought maybe she was pulling too hard on her collar and cut off her air or blood supply but she pulls just as hard in the back. Front yard hasn’t been treated with anything, has mostly Bermuda and bahia grass with a few weeds. I can’t figure out why she seizes in the front and not in back.
