Real Madrid will accept a medication called suboxone for use in dogs as a treatment for medical conditions such as Fibromyalgia, according to reports.
The Madrid-based football club said the drug would be available for use by veterinary clinics and doctors to treat dogs.
It is expected to be approved in the next two weeks, the reports said.
Real Madrid, who play at home against Bayer Leverkusen on Tuesday night, have not made a final decision on whether to bring in the drug.
This week, the club also signed a two-year contract with German firm Bayer, which is developing an inhaler for dogs to treat allergies.
