However, lumps or lesions due to tongue cancer are not always painful. Other symptoms of tongue cancer can include swollen lymph glands, especially in the neck. This is called lymphedema and may be a sign that the tongue cancer has spread beyond the tongues into the deeper tissues of the mouth and neck.
If your dog needs a plasma transfusion or any other type of blood transfusion, your vet will match your dog's blood type to the donor dog's blood type. He'll also cross match the antibodies in your dog's blood to those in the donor dog's blood, to make sure your dog doesn't suffer an allergic reaction.
Blood transfusions can be lifesaving but they are not without a small degree of risk. Giving blood from one animal to another carries the risk of transmitting infections. Blood donors are usually screened to minimise such risk and diseases that can be transmitted by such methods are uncommon in cats and dogs in the UK.
