Hi ashymee
Im sorry your boy has been poorly. I had a little dwarf rabbit (Maple) who developed head tilt and she did lose quite a bit of weight during that. She did recover and put weight back on but that was slow going. Is he on any antibiotic in case it is ear infection?
Some owners have found that an anti nausea med really helped their rabbits that had head tilt. Meclizine is one that is often used. I think it can be bought over the counter but you may want to mention it to your vet regardless. It might help with his appetite. Some vitamin B can also stimulate appetite.
How is his drinking habits?
I think I would let him come out of the hutch if he can manage it and doesn’t seem too stressed. The exercise would be good and I personally don’t think it would contribute to further weight loss. Maybe not in too open an area to minimise stress.
Much of the time, rabbits are exposed to EC early in life and some will carry it never develop symptoms. So your other rabbit won’t necessarily become sick if it is EC affecting Doge. As a precaution, it is a good idea to treat both rabbits with panacur anyway. Also, if they spend time outside, you could continue to do panacur every 6 months. I think a course of 9 days is recommended if doing twice a year.
Is Doge on a 28 day course of panacur currently? How many days has he had so far?
Sending many {{{vibes}}} his way!
