Many †hanks to Thirteen Sheep, Marcy Doane, Grey Horse, Val Ewing and Annette.
I accidentally erased all of your comments instead of posting them. Your concern for Gucci is much appreciated and I will keep you pos†ed af†er I speak to the Vet this morning.
Dancing Donkey had a great suggestion, if †he Vet has not tested her yet. I hope she does not mind †hat I posted her response as i† may help others.
You've probably already done this, but if not, talk to your vet about tick borne illness. It is Spring and anplasmosis is rampant this year. It generally presents as lethargy and anemia. Bloodwork often mimics signs of cancer and many vets look there first rather than suspect ticks. A SNAP test costs about $30. The test may show only very slight positive, but that is enough to cause anemia and renal problems. I just had this conversation with a friend, her sister's dog presented the same way you have described. The vets decided that she did not need to be tested for tick borne disease because she had been tested in the fall, they charged the owner over $1000 for x-rays and bloodwork, which were all inconclusive. A different vet looked at the case the next day and retested for anaplasmosis because it is Spring. The test showed mild positive. The dog is now doing much better after 24 hours on doxycycline. I hope that Gucci is feeling better soon and the trouble is something on Not a Good Day....
