 [ Symptoms ] my dog has started urinating in his crate at night my dog is 3 years old and is crate trained and has never had an accident in his crate until a couple of weeks ago he is been to the vet for a check up because he would not eat then when he did eat a couple of treats got sick the blood test was fine he was given a shot for the nausea and put on a bland diet for a week he is back to normal except he started urinating in his crate overnight he gets no water after 7pm goes out at 9pm up at 7am [ Disease ] hi these seem to be enlarged lymph nodes which may be secondary to a recent cest infection this will not affect your knee surgery directly but i would suggest you to get a cbc and lymph node biopsy to confirm the root cause thanks
