Unfortunately , if your bunny never had problems with his teeth before, then this overgrown front tooth is a sign of serious tooth problems overall. He likely needs his molars corrected as well as his front tooth. You will need to take him to a vet who does a lot of bunny work. He will need, anesthesia, radiographs of his head to check where and how bad the tooth problems are and then they need to be corrected. The dental problems are very likely the reason for your bunny to lose weight. Please male an appointment ASAP.

    Hello, thank you for question about Daisy. Rabbits have teeth that continuously grow. Routine dental care for trimming is very important to ensure that rabbits can chew and ingest their food properly. When rabbits do not have routine dental care their teeth can become very long and grow into their gums/cheeks as well as not align properly. This can be very painful and lead to lack of appetite. This can definitely lead to weight loss. If your rabbit has been losing weight or is showing other signs of illness I would recommend having her evaluated by a veterinarian. They can perform an oral examination to help assess her teeth and look for any other abnormalities. Hope this helps, good luck!

What do you thinkdo you think the weight loss is linked with the teeth issue as well?

I have a house rabbit that is not his usual self. I can't say I could pinpoint something that is wrong. He is just quieter than normal and not eating as much
Carefully check his teeth to see if they are overgrown or misaligned. If his front teeth are fine, have him examined by your veterinarian to check his cheek teeth. These teeth need regular trimming to prevent sharp points from developing. These points can cause discomfort and may affect appetite.

Hi my rabbit is 6 and quickly is not eating well is spread out alot his poop doesnt look right has lost weight.there isnt a vet in my area that will see him[only cats ,dogs] he isnt neutred he is my 1st bun-bun and my heart is breaking how do i keep
A rabbit that is not eating normally should be considered a veterinary emergency. If the GI tract slows or stops, a dangerous buildup of bacteria and toxins could endanger Bun Bun's life. Given his age and weight loss, he needs to be seen by a veterinarian...any veterinarian. If necessary, a specialist can be contacted by phone or online by your vet. Veterinary reference labs may provide consultation services as well. For now, offer as much timothy hay as he will eat. Offer some Oxbow Critical Care for Herbivores as well. You may be able to find it in pet stores or in the local vet clinic. Keep Bun Bun warm and as stress free as possible.

I have a double maned lionhead rabbit and i had noticed a couple days ago that hes lost alot of weight, which is odd because he always has a supply of food in his feeder so he can eat and always has water, hes eating and drinking normally so it doesn
It definitely sounds like something serious is going on with Bun Bun. If his appetite is still good and his stools are normal but he is losing weight I would be concerned with either intestinal parasites or cancer causing him to get a lack of nutrients. This would explain the hairloss as well. I would recommend taking Bun Bun to your veterinarian to be examined. Your vetnwill most likely want to run some blood work and possibly do X-rays as well. I hope this helps. Best of luck. Thanks for using Boop by Petco.

My rabbit has had a few problems and from this info I need to know if this could be contagious or if I can breed him with my doe. Maybe you can even tell me what’s wrong. It started 2 weeks ago Thumper started getting a wet chin. Later one day he got
Thanks for reaching out about Thumper and including photos. By the description and swelling on the right side of the face, a dental abscess is highly suspicious. The dental disease is making it difficult for Thumper to eat, therefore loosing weight. A veterinary visit is recommended, the sooner the better. Rarely do antibiotics solve this problem, might requiring some surgery or tooth extraction. Good luck.

One of my little bunnies has lost a lot of weight. What could be the cause?
Hello, sorry to hear that your bunny is unwell. There are many causes that can result in loss of appetite, & subsequent weight loss, really too many to discuss here. But diet imbalances, dental problems, infections, hairballs, gastrointestinal blockages, & cancer can all cause weight loss. Your bunny needs a hands on exam with a veterinarian to discover the reason for the weight loss, & hopefully get things turned around quickly. Thank you for using Boop by Petco.

My bunny Wally has been very slowly losing weight for probably 8 months now. He is 8 years old. I have read that rabbits may lose weight as they get old, like humans do. He eats normally. Only other symptom is he will now pee outside the cage on occa
Hi, Weight loss is common as animals get older, but it’s generally the result of an underlying issue like arthritis, decreased activity, or even diseases like kidney failure, liver disease, or cancer. So while it’s not unexpected to see weight loss in an 8 year old rabbit, I would be worried that Wally may have some degree of arthritis or a disease called Encephalitozoon cuniculi (EC). Both arthritis and EC can cause rabbits to urinate outside the litter box and weight loss. However, the treatment for each of these are very different and they carry different prognoses. There can also be pain associated, and therefore I recommend you take Wally to a veterinarian for an exam, blood work and radiographs (X-ray). Wally may hate leaving the house, but he will likely feel much better once he has some pain control or any other treatments that may be necessary. Good luck!

PLEASE HELP ! My rabbit is almost 4 years old. He was a really playful and a happy rabbit untill not two weeks ago , he started eating less . He would eat veggies but today he didn't want to eat anything at all . He has had diarrhea a couple of time
Thanks for reaching out about Stewie. Bruxism (grinding of the teeth) can be a sign of pain in rabbits, In addition, a decreased appetite is also a sign of pain that is originating somewhere in the body. When a rabbit eats less and has a decrease in defecation, this is termed gastrointestinal stasis. Unfortunately, there are many reasons for GI stasis to occur, including infections, tooth problems, masses, arthritis, etc. Due to the many reasons that GI stasis can occur, I would recommend having Stewie evaluated by a veterinarian. With his history of intermittent diarrhea, your veterinarian will likely want to evaluate the feces, so please bring in a fresh sample, if any is produced. Your veterinarian can also perform a thorough physical examination, and then will likely recommend some diagnostic testing to determine the underlying cause of the pain and GI stasis if there is not an obvious reason found on physical examination. They can also provide you with pain medications. Please don

I foster an American Chinchilla rabbit for a local rescue. He has one ear and is about 7lbs, but is pure skin and bones. I got him 2 weeks ago, and since then the rescue and I have been working on helping him gain weight. He's been on alfalfa pellets
You are doing all the right thing it seems, this means he must be suffering from a medical condition. i would recommend to take him to the vet in order to get him dewormed. he might also be suffering from a gastrointestinal infection that is causing this. upper respiratory infections are also know n=to cause weight loss. the vet will check him and treat him accordingly.

Why is my rabbit not eating and drinking? She's not energetic and it's normal but today my mother said her being unenergetic is not normal. When I watched over her when she was sick last week i noticed that she keeps gritting her teeth that produces
Thanks for sending the pictures of Brit. It appears as if Brit has eye discharge, possibly from an infection or blockage of her tear ducts. The tears can not drain, and then course down the side of face, causing the hair to fall out. This can also be caused by dental disease. Grinding teeth is often an indication of pain. Her head is held down and eye closed, another sign she is not feeling well. By the pictures she also appears thin, as if she is not eating well. There is no human medicine or any medicines that can be prescribed without being seen by a veterinarian. You should try and see a veterinarian as soon as possible. Also rabbits need to be spayed to prevent reproductive disease. Hope it works out well.
