The Clark Park bowl will go to the dogs this Sunday with the second annual Lug-Nuts Weight Pull and a day of protective pooch maintenance.

Low-cost vaccines and microchipping ($20-25) will be available at the park from 11 a.m. to 5 p.m. The event, sponsored by P.A.W.S. Philadelphia and the Penn Vet Animal Welfare Society, will also include advice and deals on spay and neutering.

The highlight of the day is the weight pull, which kicks off at 1 p.m. No prior training is required to enter. No registration is required either. Just a willingness to strap on a harness. Everything from poodles to pit bulls to pomeranians are welcome to give the pull a try. Entrants receive free dog food. Free dog training and gifts will also be available.
