Help... My angel is injured...

Dear fellow members

I brought my angel for her usual 90min yesterday evening, I let her run off lead because there was no other dog after 730pm. Upon reaching home, to my horror, I noticed my angel limp walk with 3 legs. I immediately checked thoroughly and noticed she injured her paw, as shown at the attached photos.
I washed her injured leg with salt water and first thing in the morning, I went to petsathome to buy this and spray 3 times a day.

She has 20g boiled chicken mixing with 50g dog food each meal normally. But now I gave her 40g boiled chicken mixing with 40
g dog food, to make her feel happier and comfortable during this difficult time. And a lot snacks when I spray her injured foot.

From observation, it is a broken toe nail. My angel didnt complain but just lay at her bed as usual, but she was less active and less responsive to my neighbor's dog bark. But if I press her injured foot, she will screams, so I know it is painful to her.

I bought her out for a walk nearby my house just now, no more park run because I didnt want her to run at the grassland and bushes. We just walked 30min until she finished her business pee and poo because she seems tire with her 3 legs limp walked. A few people passed by and saw it and talked to me being abusing my dog But I think she still need to do her business right ?

Anyway, hope to get your advice on treating her injured foot, how to make her more comfortable during this difficult time.

I bought fluffy neck pillow which will arrive tomorrow, to prevent her licking her injured paw. I bought a pair of boots, not sure if she will wear it, but hope to give extra protection to her paw during the walk.

You need to take her to a vet - foot injuries are so easily infected, and a broken nail will be excruciating.

I agree with JudyN your dog needs to go to the vets, to get the foot treated properly so it doesn't get a secondary nail bed infection and gets it nails trimmed too

Nasty injury, my running dogs over the years have had the same injury, Jessie only 2 months ago tore off her jew claw nail , her whole paw was swollen within an hour, I have in my med cabinet Veterinary Wound Powder used on horse’s applied it to the area and fortunately the following day the swelling had gone down, re applied for the next couple of days and all good. I live in a rural area and there is a agricultural store with loads of meds for the farming community. I remember an old farmer telling me anything good for horses is good for running dogs. I agree with going to the vets for serious injuries but you can treat minor ones yourself with common sense.
