Denied Care Credit, going to try with a co-applicant, has anyone been denied even with a great co-applicant?

I was really surprised when my husband was denied (my credit is no credit!) for Care Credit, now we are scratching our heads and going to see if his father will be a co-applicant, I am really nervous that even with him we will get denied, I will be devastated!!! He has excellent credit, no debt and an awesome income with a hefty amount in his bank account, plus other assets.....I was just wondering what my chances were, thanks ladies and thumbs up to those of you that everything worked out for!!
