Our spaniel badly cut it's paw on glass and needed multiple stitches. Due to the nature of the wound, this will take a couple of months to heal and there's no way a spaniel will take 'light' exercise.
We had a lace up boot, but it wasn't waterproof (and it's not been a dry summer so far), it had a soft sole (not great for an area with lots of rocks along the path) and the dog kept chewing the laces and pulling it off (before ripping the bandages off and needing another trip to the vet!).
This pair of boots has been brilliant:
+ Comes as a pair so you can keep swapping to wash/dry the dirty boot.
+ has good velcro strap that doesn't stick out so dog doesn't try to chew
+ waterproof sole so can take out in damp conditions without worrying
+ solid sole with good grip so more protection for the pad
+ dog seems to find it very comfortable and doesn't worry it
- it's not completely waterproof so water can get through the ankle if it's really wet. We've got round that by wrapping a plastic bag round it for the really wet walks and everything's fine.
- it can come off (next to impossible to avoid with a dog boot), but if you do the straps up tight and check them every now and then on a walk it shouldn't be a problem.
- it's black, like our dog so difficult to see from a distance if it's still on. Worthwhile going for a different colour to the dog if you can. Might not look as good, but much easier to see and greater peace of mind.
None of these justify losing a star, they're just watch outs.
If you own a dog, there's always a risk of a paw injury and I can strongly recommend these boots. With the benefit of hindsight and at less than £10 a pair, I would suggest buying them now to have them available in case of emergency...
