Can anyone tell me what is happening to my healthy,fit, nearly 3 year old Whippet boy please?Over the last few weeks his nails have been splitting down to the nerve and he has had to have them taken off by the vet.He is fed on good food and I don't understand why it keeps happening.The vet has given him a supplement with vitamins in and he is now on steroids and antibiotics as the infected ones have pus in.It seems to be his outer nails but the middle ones look really poor quality.He is walking with a limp.
