Cavalassur does cover treatment for lameness, but only if the cause is covered. For example, if the horse is lame after an accident, the treatment will be covered if you have chosen a contract which covers accidents. Same thing if the lameness is due to osteoarthritis for example: It will be covered only if the contract covers illness.
That's why the choice of the insurance guarantees is important when you suscribe the contract.
Have a good day,
