What do you mean with " chipped " ? Is the bone affected ?
My various female deerhounds had everything from broken toes ( 2x, clean breaks ) to rips and tears/cuts in their feet , over a torn ligament ( once ) somewhere in a paw to dislocated toes ( 2 or 3 times over the years ) . The one that took the longest to heal was the ligament , made worse by the winter condidtions as the (outside) toe of course moved a lot in the snow. All I did was homoeopathy and eventually a shoe with a hard sole for the walks . This is basically I do for all foot injuries - both broken toes completely healed up in about 3 weeks ,same goes for the dislocated ones and with wonds it depends . I do use a cleansing cream ( befedo ) on some wounds , at least intitally .
If there is a lot of swelling I usually use " heparin " ointment , which helps to bring it down . And , always , always the homoeopathic arnica pellets ((and whatever else remedy might aply to the injury ) .
All the best - he will be fine again in a jiffy !!!!
