Grain-Free Diet Guidance

Recent information has given rise to concerns about feeding grain free diets. There is increasing evidence linking these diets to a form of heart disease in dogs. The FDA, Tufts University, UC Davis, CVCA and others continue research regarding these concerns. For now, here are links to related information, as well as a statement from our local cardiology group.

From the Chesapeake Veterinary Cardiology Associates (CVCA) Website; Guidance for Pet Owners:

“At this point in time, we are not certain of the exact causal relationship between grain-free and/or high legume diets in atypical dog breeds with dilated cardiomyopathy (DCM). Taurine deficiency of these pet foods does not appear to be the primary issue in these DCM patients as we have found normal taurine levels in many of these pets with DCM. However, in some breeds such as the Cocker Spaniel and Golden Retriever, we have found low plasma taurine levels.”

At this time, if there is not a clinical reason (i.e. food allergies or gastrointestinal upset) for use of a limited ingredient, unique protein source (kangaroo, alligator, bison, etc.) diet, we would suggest using alternative diets. Consultation with a board-certified veterinary nutritionist should be considered. Another possible consideration is to use two/three pet foods from different manufacturers including a diet that is not full of legumes (lentils, chickpeas, peas) and has some grain in the product. As we continue to investigate the link between the increased incidence of dilated cardiomyopathy in atypical canine breeds with grain-free diets, we hope to ultimately determine the definitive issue but, for now, we currently do not have that answer.”

Neutering in Rabbits

What is neutering?

Neuter is also referred to as orchidectomy or castration. It is a surgical procedure in which the testicles are removed in order to sterilize or render infertile, a male animal.

Why should I have my rabbit neutered?

There are many behavioral and health benefits associated with neutering your rabbit.

  • The obvious benefit is the elimination of unwanted pregnancy if there are intact females present. Although raising baby rabbits might be a wonderful family experience, finding homes for the new rabbits might prove more challenging than one might anticipate.
  • Neutering eliminates the risk of testicular cancers. Reproductive cancers are relatively common in rabbits.
  • Neutered rabbits are much less likely to display undesirable hormone induced behaviors such as mounting, urine spraying (or territorial marking) and aggression.
  • Litter box habits are more stable in neutered animals.
  • Your rabbit may be calmer and easier to handle as it is not experiencing the stresses of sexual frustration.

When should I have my rabbit neutered?

Most rabbits are neutered between four and six months of age. Many veterinarians prefer to neuter at 6 months of age

What does a neuter surgery involve?

This surgical procedure is done under general anesthesia. You must NOT fast your rabbit the night prior to surgery as is done with other animals. Your rabbit will be given a physical examination prior to the operation. Your veterinarian may recommended some pre-operative blood tests. This is to ensure your rabbit is healthy enough to have surgery performed and that there are no pre-existing problems that may compromise your pet. The operation is performed through a small incision in the scrotum or just in front of the penis at the base of the scrotum. The hair in this area will be shaved and surgically prepared prior to the surgery. The testicles are removed. The surgical incision will be closed with sutures under the skin. Most rabbits go home within 24 hours after surgery.

What post-operative care will my rabbit need?

Your rabbit will likely be given pain medication in hospital and may be sent home with several days worth of the same. Keep your pet in a clean, quiet environment and try to minimize excessive running, jumping or hard play that may stress the incision. Feed your rabbit normally, and your should expect he will be eating and drinking within 12-24 hours. Inspect and assess your rabbit and the incision several times daily and report any concerns regarding behavior changes, appetite, drinking, urination and defecation to your veterinarian. Occasionally, rabbits will chew the sutures and open the surgical wound. This needs immediate veterinary attention.

Are complications common with neutering?

In general, complications are rare with this surgery. However, as with any anesthetic or surgical procedure, in any species, there is always a small risk. To minimize risks, it is important to follow all pre-operative instructions and report any signs of illness or previous medical conditions to your veterinarian prior to the day of surgery.

The potential complications may include:

Anesthetic reaction: ? Any animal may have an unexpected adverse reaction to any drug or anesthetic. These reactions cannot be foreseen, but are extremely rare.

Internal bleeding?: This may occur in association with any of the cut or manipulated tissues. This is very rare and is more likely to occur if your rabbit is too active in the days following the surgery. Signs to watch for include weakness, pale gums, listnessness, poor or absent appetite, or a distended abdomen.

Post-operative infection?: Although rare, this may occur internally or externally around the incision site. Infection can be managed with antibiotics. Infections most commonly occur when a pet licks the surgical site excessively or is kept in a damp dirty environment. Monitor the surgical site several times daily for swelling, redness, wound breakdown, pus, or other discharge.

Suture Reaction or Sinus Formation:? This is extremely rare but occurs when a sensitive body reacts to certain types of suture material used during the operation. This results in a draining wound or tract that may appear up to several weeks after the surgery was performed. Further operations may be required to remove the suture material and correct the issue

Will neutering have any adverse effects on my rabbit?

The vast majority of rabbits will experience no adverse effects following neutering.

There are many myths and beliefs about neutering that are not supported by facts or research. Your pet will not become fat and lazy.

Feel free to discuss the pros and cons or any concerns you may have with a veterinarian familiar with rabbits.
