If they are very wobble it hints that they are not attached to bone and wouldn't be too much of a problem to remove. It might take a while to heal but if he's prone to scraping himself with his rear dew claws then it might be beneficial to remove them while you can.

I don't like this 'remove bits just in case' mentality. My dogs run through grass, forests and beaches and their dew claws don't catch.

Dewclaws may contribute to improved balance, too
Dewclaws are another &equently amputated dog part that are often thought to be use¬less, but in fact, the front dewclaws do have a purpose says Chris Zink, DVM, PhD. "The function of front dewclaws is to prevent torque on the leg," she says. "There are five tendons attaching the dewclaw to five muscle bundles, supporting this function¬ality. When a dog is running, the dewclaw comes into contact with the ground. If the dog needs to turn, the dewclaw digs into the ground to support the lower leg and pre¬vent torque."
"The rear dewclaws are vestigial in most breeds; that is not true for the front dew¬claws, which should be more correctly called digits or thumbs," says Dr. Zink. She works exclusively with performance dogs and has found that if a dog doesn't have dewclaws, the leg will twist when turning, which applies significant pressure on the leg. to the toes. carpus, elbow, and shoulders. The repeated twisting and pressure can ultimately cause chronic painful conditions, especially carpal arthritis. "Of the over 30 dogs I have seen with carpal arthritis, only one has had dewclaws. All the others had them removed," says Dr. Zink.

Hia all
Flynn has Dew claws on each foot, is that strange??
Sorry if i sound vague but all other dogs i have had have only had two!
Anyway..the vet said when he is castrated he can take them off, which i thought about due to him catching one of the rear ones before but is this unnessecary pain?
Does it take long to heal?
Any thoughts welcome and appreciated
