Dog’s peeling paws worry owner

-

Q: Recently, I walked my 8-year-old female Dalmatian, Sadie, through an area I thought was brown, dead grass. After about 10 paces she suddenly stopped walking and looked at me in discomfort. I looked at the ground more closely and realized we were actually walking on dead thistle-like plants with hundreds of sharp, spiky balls. I picked her up right away and carried her out of there.

A few days later, all four of her paws started peeling and scaling, almost like a sunburn. I’ve since observed that no plants grow on this hillside, and I now suspect that I accidental­ly walked her through something like Roundup. She spent a lot of time licking and grooming her feet and I’m concerned about the long-term effects of whatever chemical she walked through. A: It’s difficult to say what Sadie was exposed to. Chemicals can cause irritation on contact. Products like Roundup are generally not life threatenin­g if ingested in small quantities. The most likely signs you would see associated with ingestion would be gastrointe­stinal upset with vomiting or diarrhea. These signs would probably occur soon after ingestion.

If you are ever concerned about a product Sadie has been exposed to, the ASPCA has a great poison control website that you can access at www.aspca.org/pet-care/ poison-control. The site has informatio­n on many substances, plants, etc., and there is also a phone number you can call for more informatio­n.

The sloughing of her paw pads could be due to chemical irritation as you were concerned about. There are many other potential causes for these signs, however, including dermatolog­ic and metabolic conditions. It is possible that it was a coincidenc­e that you went for a hike a few days before the paw pad signs started.

Also, there are many things that can cause middle-aged to older large-breed dogs to “slow down” as you described. We commonly see largebreed dogs with some degree of arthritic changes appearing slower one to two days after a long hike or exercise.

As always, I recommend having Sadie evaluated by your regular veterinari­an if she is not feeling better or if her signs return.
