Why dog attacks?

Dr. Ian Dunbar explains dog behavior.

Dr. Dunbar received his veterinary degree and a Special Honors degree in Physiology & Biochemistry from the Royal Veterinary College (London University) and a doctorate in animal behavior from the Psychology Department at the University of California in Berkeley, where he spent ten years researching olfactory communication, the development of hierarchical social behavior, and aggression in domestic dogs.

Dr. Dunbar has written numerous books, including How To Teach A New Dog Old Tricks, the Good Little Dog Book and a series of Behavior Booklets: separate educational booklets on each of the most common pet behavior problems.

What are the historical findings in heart failure?

• Syncope/lethargy - due to reduced cerebral perfusion.
• Weakness/reduced stamina - due to reduced skeletal muscle perfusion.
• Dyspnea/wheeze/cough/orthopnea - Dyspnea is due to pulmonary edema or pleural effusion. Cough may occur due to pulmonary edema or due to mitral valve insufficiency with left atrial enlargement and compression of the left main-stem bronchus; this latter cause may often occur in the absence of congestive heart failure. Many dogs with heart failure may not cough, whereas dyspnea, wheezes and sometimes orthopnea (difficulty breathing when lying down) are common historical findings. Some dogs will cough with relatively mild edema and others only cough with severe pulmonary edema. It appears that the speed with which the pulmonary edema develops may play a role in determining when or if cough is to develop.
• Abdominal distention - due to ascites and/or Hepatomegaly or splenomegaly.

What is the best solution for dog warts?

There are a lot of reasons for little wart like bumps on dogs. True warts are caused by a virus and will generally go away over time when the body recognizes the virus and produces antibodies to fight them off. Another cause of little bumps like this would be what are called skin tags. These are just little skin projections, usually not very hard, that appear and are not dangerouss or necessary to remove. There can also be little bumps that appear when an oil gland duct gets plugged so that the accumulation of the oily material increases and eventually results in a bump. Obviously turmors, both benign and cancerous, can also cause this appearance, but your veterinarian can get a good idea what the problem might be by sticking a needle in them, pulling out some cells, and looking at the cells under a microscope. Most likely these are not problems and really do not need to be removed, but the next time you are in the veterinary office, just ask for an opinion of what they might be.
