Boltz tested NORMAL for the mutated gene associated with Degenerative Myelopathy, meaning he does not have the mutation commonly known to cause the development of DM. Our vet decided to start treating him for Myasthenia Gravis, and if that is the cause, we would expect to see improvement in a week. Based on the extensive tests that have already been completed, the one remaining diagnosis being discussed is degenerative peripheral neuropathy which can be diagnosed by a nerve or muscle biopsy, but has no treatment. Since this condition has no treatment, our local vets and the neurological specialists concur that this more more invasive test would not be recommended at this time.

After Denali’s retirement on October 16th, Axel and Grayson needed some time to adjust to the change. I made the decision to retire Denali based on his advanced age needing some time to recuperate from a paw wound. On a younger animal, this would have been something that we would have treated within the pack, but an injury at this age increased his vulnerability. Since Denali’s retirement was not a situation where the arctics forced him out of the pack, we saw more stress howling, especially from Grayson. After about a week, the howling seemed to subside and Grayson has increased his displays of dominance, especially on the weekly deer carcass. Based on our experience with Shadow and Malik, the last pair of arctic wolves we managed, we know the winter will certainly be active for these two.
I don’t have anything to post on Boltz today, we are waiting for additional spinal tap test results to come in (if you recall, there were 3 tests). So, far everything has been negative and bloodwork is all in normal range. I have copied one of the reports here to see all the things that have been ruled out in this challenging time trying to get a diagnosis. The Vet put him back on prednisone as his condition was declining since we weaned him off of the prednisone to do the spinal tap. Now, we are closely monitoring him by camera and visual checks to assess if prednisone is working. Staff are diligent in reducing any distractions in the wolf yard that might impact his ability to comfortably rest. I hope to have more answers by the Monday Working for Wolves webinar at 5 pm Central time. There are still spots available for this webinar if you would like to register check our our Programs – Webinar tab on the website at www.wolf.org.
If you are a webcam viewer, you may have noticed that Denali and Grizzer are sharing the East Side Retirement and the Back Habitat. While reuniting the retired pack members was in my ongoing management plan, we had planned to wait until Denali was done with his antibiotics later this week to avoid food competition with medications. Apparently, Denali didn’t think much of my plan.
At 3:36 am this morning, In less than 30 seconds and with no agitation, Denali grabbed the gate frame, twisted the hinge on the gate (which staff couldn’t move with a pry bar and sledge hammer) and joined Grizzer in the Back Habitat. As a management policy, all external gates and gates between retirement and the Exhibit Pack are chained so if a gate hinge is compromised, the gate is still secure (we had an issue in 2008, where Lakota was reunited with the Exhibit Pack, led by Aidan and Denali). We also chain all external gates in the East Side Retirement area and Pack Holding Area, but since Grizzer has a history of grabbing chains in his younger years, we hadn’t used chains on the internal gates in retirement, except where Grizzer shares a gate with Boltz. The gate that Denali opened was an internal gate into the transition area. We have been watching Grizzer and Denali since last friday and all indications were good for a compatible introduction, the surveillance video confirmed our thoughts. Once again, we are so grateful for those of you who support our camera upgrades and robust surveillance system through generous donations. After this morning’s events, wolf care staff are now placing gate chains on ALL gates. One can’t assume that because wolves are older, that they won’t still act like wolves.
As Walter, one of our camera wolf watchers states: “They are not old, they are seasoned: as in there is very little you can throw at them or put in front of them they haven’t seen before or know how to deal with, including (apparently) wood reinforced chainlink metal framed gates”
If we find that Grizzer doesn’t like the arrangement, we will go back to keeping them separate, with a bolted gate. So far, Grizzer is following Denali around and it hasn’t impacted Grizzer from claiming his favorite spot in front of the Back Habitat den. Although since the weekend, he is not using the cover hay, so he may be getting some pain relief from the cold ground on his tendon. It is a form of self-medicating; Luna used to do the same thing.
Boltz is still being maintained separately in the Pack Holding Area until we have additional test results back. We ruled out cancer of the spine, bacterial or fungal issues, no meningitis, no tick related issues, no blastomycosis, the list is getting shorter. We will continue to host a separate log for Boltz under the Meet our Wolves section of the website
So far, the test results we are getting don’t show any abnormalities in the bloodwork. As I said in previous logs, he is otherwise in good health and doesn’t appear to be having a pain response, but his strength in his back legs is compromised. We received some preliminary results on the spinal tap and according to the lab report
” No obvious infectious etiologic (causing or contributing to the development of a disease or condition.) agents, malignant neoplastic cell populations (cells that could potentially invade and metastasize into cancer) , or atypical particulate matter are identified. The critical thinking and waiting game on additional samples continues.
With the Retirement of Denali on Friday, Grayson has increased his howling, intensified to more bark howling when there is any activity in the wolf yard and even got his brother Axel to bark howl with him today. Wolves are neophobic (hesitant about new things) and they don’t like change, especially Grayson. But, change will happen. Cold weather arrived on Saturday putting a layer of ice on the pond and reminding us that winter is upon us and we can expect wolf behavior to increase. Another change is that without Denali to possess food, Grayson is free to take the lead on the carcass. The following was a daily report from the Center educators that monitor the pack dynamics on a daily basis:
As you may have read in the Exhibit Logs, we retired Denali on Friday. Denali came to us in 2008 from the Wildlife Science Center in Forest Lake and has been an active part of the Exhibit Pack for 12.5 years. From what we can see from the surveillance cameras, there was some dominance over the deer carcass that resulted in Denali getting a bite on his back right leg near his Achilles tendon and his paw. The vet was here doing an assessment on Boltz and she advised that Denali needed a treatment of antibiotics, some rest to heal his pad, since these are notoriously hard to heal if activity isn’t restricted. With colder temperatures and snow predicted for the weekend, we knew activity was only going to increase with the younger pack mates and food possession, so we decided to move him into the East Side Retirement area permanently. Another additional circumstance related to Denali’s overall health. In May’s medical exam the vet identified one of his five biopsies showed a potential mast cell tumor, so this is an appropriate time to begin the next stages of his medical care. Since this was not a forced retirement, meaning the other wolves didn’t force him out, there is some bark howling behavior coming from Grayson and Axel due to the change in pack dynamics. Denali is transitioning to the new location, but in order for him to take his antibiotics, he is restricted to smaller meals twice a day. We would like Denali to lose a bit of weight and want to make sure he is always willing to take his medication. This was a bit of a problem when he was in the Exhibit. He would gorge on a deer carcass, then become finicky about his daily meds. Today is the 4th day of his retirement and so far the plan is working. We anticipate Boltz and Denali can share the same area, but we need to wait for results from the recent tests on Boltz before we change anything in his life.
We are reconfiguring our gate system to allow for Grizzer to resume access to the front of the Pack Holding Area. As winter advances, we definitely want him closest to the heated building. Until then, Grizzer is very content in the back habitat and Boltz is content in the Pack Holding Area enjoying the new cover hay placed by the wolf care staff over the weekend.
