Hi All I'll apologize up front of this is long but I need to unload my frustrations and fears on a group who will understand ...... I have an 11-3/4 year old yellow lab Daisy. She has from a young age (4 months) had loads of issues/chronic problems. I have dealt with them all as they come, and continue to do so now. Always soldiering on along with her, through all her health troubles, arthritis in front/back legs, hip dyslasia, food/environmental allergies and accompanying skin issues/, GERD/reflux, hypothyroidism, did I forget anything? Oh yes - glaucoma in right eye and subsequent blindness (April of this year). The vet's file on her is so thick. So end of October after all summer of Daisy keeping us awake at night howling/barking, I took her to vet and we did a geriatric blood panel to see if it may be senility causing the howling. It was discovered that her tests came back fantastic (huh?) on all levels except her thyroid (usually low - has for years taken thyroid supplement twice daily) had gone too high. So, we cut back her thyroid meds to one a day and the vet suggested that the howling could be restlessness due to high thyroid levels. Needed to wait at least 3-4 weeks to see if any changes. Here we are almost 4 weeks later. Daisy has stopped howling at night (YAY), but now: Since Nov 6 she keeps going "blind" in her one good left eye sporadically. It usually happens in the morning, and usually lasts 1/2 hour to 2 hours. Two - three times a week. It has happened later in day, but almost always is in mornings. So off to vet again last week. He looked at left eye (she was seeing at that time) and said it looked OK. Retina was fine. Didn't see any sign of glaucoma. He wondered if she was having seizure prior to blind episodes. I haven't noticed anything. Just one minute she can see, the next she can't. The vet was interested in the "episodic" nature of her blindness but couldn't really offer any explanation. So yesterday morning she got up and was "blind" from the get go. It went away after an hour or two, but she seemed quiet for the day and well she ate her breakfast, was not that interested in food the rest of the day, or even this morning. She did eat but it took her some time to go to her bowl. Her norm is to eat everything as soon as it hits her bowl, so something is up. Funny she ate her piece of morning toast up with her usual enthusiasm so I'm not sure what her deal is. I worry for her. It is a constant for me. The poor thing just has one problem after another her entire life. Has anyone experienced anything along the blindness issues like this? I am worried this is a sign of a bigger issue, and now the lack of food interest.....concerning. I am holding off getting in touch with vet, as she is still eating/drinking.
