Hi Connie, welcome to TP
No one can "put2 someone in a home against their wishes so if your father still has the capacity to object to the move they may find it difficult as the home will need to get a "Deprivation of Liberty Safeguarding" order (DoLS) and to do that social services will need to get him assessed and show that his needs can only be met in a care home.
Social services are required to use the "least restrictive option" and a care home against someone's own or families wishes isn't something they normally do unless they have concerns about the carers (you in this case) have the ability to care for him correctly.
My wife is subject to a DoLS at the moment (with my consent) as I could no longer care for her at home, she had to be seen by a social worker and Independent Mental Capacity Advisor (IMCA) and a psychiatrist to confirm that although she wanted to go home he needs could only be met in a nursing home. We then had a "best interests meeting" and all agreed it was the only option, getting a DoLS isn't a simple process and you'll find a lot of homes won't take people against their wishes specially if they're mobile and might try and get out or physically able to resist their care.
