THIS is why you do not walk your dogs on asphalt or concrete in the summer. If you see someone walking their dogs on asphalt or concrete, PLEASE educated them and get the pet to cooler ground. Original post was from Pet Ambulance Victoria

This should be sent to all the veterinarians including the specialists!


We have received two notices. (1) Nails wrapped in cheese at dog parks in Chicago and Massachusetts (see pic). (2) from some friends that in Augusta Maine dog park, antifreeze is being found in doggie water bowls. Please beware and be careful and PLEASE SHARE and spread the word

Ever wonder where puppy mill dogs come from? Here's an example. Many get cooked alive in the sun and freeze to death in the winter. If you purchase your dog from a pet store, I can guarantee your "AKC" certified dog came from a place like this.  This one is even better than the ones  I saw in Iowa and Missouri!

Do you recognize she is a Yorkie?
Please do not purchase your pet from a Pet shop, Backyard breeder or Commercial Puppy Mill.

"Fun at the Beach"

"Fun at Work"

This is a real combination of symptoms that spells out EMERGENCY. These are the classic symptoms of a condition referred to as "bloat" - a dog that is pacing, restless and has unproductive attempts to vomit.

This is a common problem in large breed deep-chested dogs but can also occur in smaller dogs.

Basically what happens is this - the stomach twists causing the blood supply to the stomach to be compromised then leads to tissue death. As tissues are damaged, toxins are released and a sequence of events occurs that if left untreated, leads to death.

If you ever notice these symptoms in your dog, call your local veterinarian or emergency clinic as soon as possible.

This is a condition that is fairly common and often occurs in the evening or nighttime hours. It is also a very expensive condition to treat.  READ MORE...


Dealing with Excessive Barking

The first step to stopping barking is to understand why it is happening. Dogs bark for all kinds of reasons, including anxiety, boredom and/or loneliness. Sometimes they bark just because it feels good.  Luckily, most dogs will respond to one or other intervention to curtail their barking. Whether you simply bring an outdoor dog inside or take the time to apply behavior-modification techniques, you can cause a dog to be less of a nuisance and to be more socially acceptable.

Removing Skunk Odor

No need for the tomato juice. Use a mixture of 10 parts hydrogen peroxide to 1 part baking soda. Add a dash of degreasing dishwashing soap and pour into a spray bottle. Spray liberally over dry coat and allow to air dry. Avoid eyes. Works on other objects, too!

Causes of Hair Loss (Alopecia) in Dogs  Holly Nash, DVM, MS

There are many diseases and conditions which can cause a dog to lose hair. Some of these may be considered normal, others can indicate a serious disease is present. Most of the conditions which result in hair loss are included in the table below, though some of them may be rare. This extensive list helps you understand why a quick diagnosis may be difficult to make, and various diagnostic tests may need to be performed. The most common conditions causing hair loss are color-coded gray in the table (some may be more common in certain geographical areas).
Veterinary Services Department, Drs. Foster & Smith, Inc
Condition Description Symptoms Diagnosis Treatment
Acanthosis nigricans Inherited form seen in Dachshunds; secondary form caused by friction, hormonal abnormalities, or hypersensitivities Darkening of the skin; in secondary form see scratching and hair loss History, physical exam; in secondary form, testing to determine underlying cause Primary: no treatment; secondary: treat underlying disease; in some cases, steroids and Vitamin E supplementation
Acral lick dermatitis (neurodermatitis) Self-licking in dogs results in self-trauma; possible causes include anxiety, boredom, stress (e.g., new member in household); licking can develop into an obsessive behavior Red, hairless, well-circumscribed, sometimes raised lesion usually on the leg; if chronic, will drain Exclude other causes; history important Relieve underlying cause e.g., anxiety; restrict licking, e.g., elizabethan collar; behavior modifying medication may be necessary
Adrenal sex hormone responsive dermatosis More common in Pomeranians, Chows, Keeshonden, and Samoyeds Hair loss starts on neck, tail, back of thighs, and progresses to trunk; dog appears to have a 'puppy coat'; skin darkens Biopsy; eliminate other causes Mitotane is optional
Allergic and irritant contact dermatitis An allergic reaction following exposure to antibiotics applied to the skin; metals such as nickel; materials such as rubber, wool, and plastic; and chemicals such as dyes and carpet deodorizers; or inflammation caused by irritating substances such as poison ivy. Generally requires multiple exposures. Red skin and small bumps or blisters on the areas of skin that are sparsely haired and directly exposed to the offending substance, itching; hair loss in chronic conditions Patch test, exclusion trials Restrict exposure to the allergen or contact irritant in the dog's environment; steroids, antihistamines
Alopecia areata Thought to be an autoimmune disorder Patches of hair loss especially on head, neck, and body; no itching Microscopic examination of hairs; biopsy Usually recover spontaneously
Atopy (allergic inhalant dermatitis) Allergic reaction to something the dog inhales such as pollen, house dust mites, and mold Licking of feet, inflamed ears, itching, redness, and hair loss; sometimes development of infection or hot spots Intradermal or serologic (blood) testing for allergies Reduce exposure to allergen (what the dog is allergic to); steroids, fatty acid supplements, biotin, antihistamines, shampoos, immunotherapy

Cheyletiella (rabbit fur mite) mange Infection with the Cheyletiella mite Itching, scaliness; some hair loss, if severe Skin scraping and microscopic examination - the mite is often very difficult to find Pyrethrin, Permethrin (Do NOT use permethrin on cats.)
Color dilution/mutant alopecia Hereditary condition affecting dogs with blue (diluted black) or fawn coat colors; more common in Dobermans, Dachshunds, Great Danes, Yorkshire Terriers, Whippets, and Greyhounds Hair in the blue- and fawn-colored areas starts to thin at around 6 months of age; secondary folliculitis often develops Breed; history; and coat color None; avoid excessive grooming or harsh shampoos; protect skin to prevent secondary bacterial infections
Congenital hypotrichosis Congenital lack of hair Puppies born with little or no hair; any hair they are born with is lost by 4 months of age Physical exam; biopsy None
Cushing's disease (hyperadrenocorticism) Caused by an increase in corticosteroids in the body - either due to increased production by the body or as a side effect of high doses or prolonged therapy with corticosteroids Hair loss, thinning of skin, hyperpigmentation, easy bruising, seborrhea, comedones (black heads), may see calcinosis cutis; lethargy, increased thirst and urination, potbellied appearance Adrenal gland function tests, urinalysis, chemistry panel, CBC If due to glandular tumors, selegiline, o,p-DDD (Mitotane), or surgical removal of tumor; if due to high steroid doses, withdraw use of steroids slowly

Folliculitis Infection of the hair follicles, often with staph bacteria; symptoms usually appear on skin with less hair, such as the abdomen Pustules form in follicles and break open to form 'bull's-eye,' 'annular,' and 'target lesions,' which have crusty centers and red or darkening on the periphery, and 'epidermal collarettes,' which appear as rings of scaly skin; may itch; short-coated breeds may develop small tufts of hair, which are lost; breeds with long coats may have seborrhea Skin scraping; culture; biopsy Antibiotics for at least 4 weeks - continue antibiotics 10 days beyond the apparent cure; if recurs, look for underlying problem such as allergy or hormonal imbalance
Food allergies Allergic reaction to something in the diet Licking of feet, inflamed ears, itching, redness, and hair loss; sometimes development of infection or hot spots Food elimination trials Change in diet
Granulomas May be due to infections; the body's reaction to foreign material such as plant material (e.g., foxtail) and suture material; other constant irritation; or unknown causes Solid firm nodules of varying sizes; those due to foreign bodies often have draining tracts; may develop hair loss, ulcers, and secondary infections History, clinical signs, biopsy, surgical exploratory Surgical removal of the foreign body (in the case of plant material, tracts may be extensive and require major surgery); antibiotics if infected; treat any other underlying cause
Growth hormone responsive alopecia Not well understood; thought to be caused by an enzyme deficiency or decrease of adrenal hormones, which allows certain other hormones to accumulate in the body: more common in Pomeranians, Chow Chows, Keeshonden, Samoyeds, and Poodles Hair loss on neck, tail, and the back of the thighs; skin darkens; usually starts when dog is less than two years old Hormonal blood testing Neuter animal; growth hormone; hormonal supplementation
