How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

A collapsed trachea is a very common health issue in Pomeranians which is due to the fact their neck and windpipes are very small. The condition can either be inherited or it can be the result of wearing a collar and pulling on the leash which puts pressure on the windpipe and can cause it to collapse.
Because dogs cannot sweat like their humans, they need to breathe fast to allow air to circulate efficiently through the body. Fast breathing allows a dog`s body to get back to a normal temperature.
What is a normal resting/sleeping breathing rate for dogs and cats? In general, all dogs and cats, with or without heart disease, have a breathing rate of between 15-30 breaths every minute. Lower rates are even possible and are no cause for concern as long as your pet is otherwise healthy.
On average, it takes Pomeranians around about two months, roughly 63 days, to complete their gestation period.
The simplest way to prevent bad dog breath is to brush your dog`s teeth on a regular basis. Teeth brushing reduces plaque and promotes better oral hygiene, much as it does in humans, and with a little training, most dogs learn to enjoy having their teeth brushed. Dog toothpaste is formulated for dogs.
You should be able to hear your Pomeranian breathing while he is sleeping, however there should not be a loud pant. It is normal, however, for canines to have brief moments of heavy breathing while experiencing dreams.
Rapid breathing allows a dog`s body to get back to a normal temperature. However, if your dog is breathing above 40 breaths per minute while at rest in a cool and calm environment, or they appear to be struggling to breathe you should seek emergency veterinary care.
For many dogs, it will happen randomly throughout their lives. It is theorized that it may be triggered by irritations to the nasal passages, such as in the case of allergies; however others have suggested that it can happen due to over-excitement.
Heavy breathing in dogs can be caused by upper or lower airway conditions, congestive heart failure, pleural space diseases, pulmonary thromboembolism, abdominal distension and even non-respiratory causes such as stress or metabolic acidosis.
In order to abide by most Kennel Club rules, your Pomeranian can only have one litter per year. In some circumstances, 2 litters in 18 months are permitted.
Abscesses or cavities in the mouth and teeth often cause fishy smelling breath. Plus, foreign objects – like food or sticks – can also get lodged in the mouth and cause a foul smell. Sadly, it`s estimated that 80% of dogs by the age of two are affected with some degree of dental disease.
The REM phase is unique to mammals, like your precious pupper, and comes with a high amount of brain activity. During this period, a dog will need more energy. They`ll start breathing faster to take in an excess amount of oxygen, which can then be transferred from the lungs to the bloodstream and converted to energy.
Your dog might be shaking or panting because they`re having difficulty getting enough air. Panting allows your dog to take deep, rapid breaths. This can be caused by several health issues, like heart conditions or lung issues, and can indicate a need to go to an emergency vet.
The long guard hairs do work to help block the sun`s rays but the compacted undercoat blocks air from circulating. This can cause a Pomeranian to get very hot and overheat.
Post-Partum Complications in Dogs

Generally, this condition occurs within the first week after giving birth. Symptoms include fever, lethargy, loss of appetite, fetid vaginal discharge, dehydration, fast heart rate, panting, vomiting, and diarrhea.

Unusually loud breathing sounds are often the result of air passing through abnormally narrowed passageways, meeting resistance to airflow because of partial blockage of these regions. The origin may be the back of the throat (nasopharynx), the throat (pharynx), the voice box (larynx), or the windpipe (trachea).
Signs of ARDS include increased respiratory rate, blue discoloration of the skin and mucous membranes (gums, insides of the eyelids) due to poor oxygen delivery, and, occasionally, coughing. Some affected dogs may have pink, foamy fluid from the mouth or nose, which is coming from the dog`s lungs.
These sounds of grunting or oinking are actually called reverse sneezing. Reverse sneezing is when a dog`s throat muscles spasm and soft palate are irritated. The dog will breathe in too much air through his nose and thus begin the worrisome sound of your dog sounding like a pig.
When a dog gets stressed or anxious, their heart rate increases. This means that more oxygenated blood is pumping through the body, demanding more oxygen from the system. This results in a dog hyperventilating.
Usually caused by lung and respiratory problems, breathing problems can also be indicative of other problems such as obesity, heartworms, tumours, heart problems, allergies, or injury and trauma. When your dog has difficulty breathing, you may notice fast, laboured breaths, a wide-open mouth and an extended tongue.
There is no exact official age of becoming a senior. Small toy breed dogs such as the Pom can be considered to be a “Senior” as early as 7 and usually no later than 9. In general, it is safe to say that the senior years begin at 8 years old.
1 year old: Adult; official an adult at this age (and the human equivalent of 15 year old teenage, the 1 year old Pomeranian has lots of energy.
Depending on the breed, pregnancy can range from 56 to 69 days, with smaller dogs generally giving birth slightly earlier.

Q. My Pomeranian is about 49 days gestation. She is breathing rapidly and seems to have trouble being comfortable. Is there anything to be concernedabout
ANSWER : A. An exam with your vet would be prudent. If she is eating, drinking and eliminating normally though, her discomfort is likely due to her increasing size.

Q. I have 3 shihtzus 2 have diarrhea seem fine otherwise I did change there diets in the last 3 days for all. They eat imams canned food twice daily now
ANSWER : A. Some dogs have more sensitive stomachs than others so a change in diet may have been enough to cause it. Did you introduce the new food gradually? We normally recommend doing it over 7-10 days (a quarter of new food with 3quarters of the old food for a few days, then half and half for a few days etc). Was there a reason for changing their diet? If they were fine on the original food then stick to that. If the diarrhea doesn’t clear up in a few days then get some pro biotic paste from your vet.

Q. 3yr old chihuahua mix. Has had shots. Seems to wheez when sleeping. Why is that?
ANSWER : A. It may be a conformational thing, in other words the way he’s put together. He might have a long soft palate (on the roof of his mouth) or slightly small nasal openings, and either of these things might cause him to make increased respiratory noises when he’s breathing deeply.

As long as he’s normal otherwise – eating/playing, urinating and defecating normally, not seeming out of breath or like he doesn’t want to move, and not breathing abnormally when awake – I think you could mention this to your vet at the next visit. He can listen with a stethoscope to hear any abnormalities. He may recommend chest x-rays to see if there’s anything unusual in his lungs.

Q. My dog is what seems to be having trouble breathing taking short breaths
Hasnt been herself sleeps and lays around alot losing weight rapid why?
ANSWER : A. Without examination it is impossible to say. It could be due to heart, liver or kidney failure or possibly cancer. You need to see your vet as soon as possible for an examination and investigation. Probably blood tests and maybe an xray.

Q. My dog hasnt eaten snce I left 4 days ago. I won’t be home for 6 more days. How can the caretaker get her to eat?
ANSWER : A. If your dog is feeling a bit sad while you are away and is refusing to eat, your pet sitter may try some things such as adding in boiled chicken or turkey to meals to encourage eating. A pet-safe gravy may also entice your dog to eat as well while you are gone. Your pet sitter may also want to offer smaller meals more often throughout the day to give your dog more chances to try and eat when she is feeling more comfortable and a little less sad. A game of fetch or playing together may also get your dog’s appetite going and help her to feel more comfortable eating around your pet sitter.

If your dog is showing any other signs of illness in addition to the refusal to eat (beyond normal missing an owner), then it is always a good idea to keep an eye out and contact a veterinarian as needed.

Q. I recently moved. My dog was close to my husband. He seems fine but sometimes he seems sad. I work part-time. My husband used to be home. Any tips?
ANSWER : A. Separation Anxiety and sadness when away from a close family member is very common in dogs. They may become depressed or destructive when left alone. However, providing some things to help your dog feel better can help during the times when you are away from home.

A treat or puzzle toy such as a Kong stuffed with yummy treats or even a portion of the day’s food can keep your dog occupied while you are away. Freezing the food in summer, or adding in treats that are only given when you are away can add to the challenge and help make the toy something special to look forward to.

Turning on a television or radio to a channel such as talk radio can also help by providing sounds that are familiar to your dog and may provide comfort while you are away. Many TV providers also now have “dog and cat” channels with programming designed just for pets that are home alone! Adding in a blanket or article of clothing that smells like you can also help to soothe your pet while you are away, making him feel more comfortable.

Q. My French Bulldog (11 months) threw up after eating and is dry heaving, plus he’s not acting normal. His breathing is nasally and he’s lethargic. Help
ANSWER : A. Vomiting is a common symptom that can be a sign of numerous health issues ranging from minor digestive upset, to bloat or internal illness. If the vomiting has only occurred once and everything else is normal, a bland diet of plain boiled chicken and white rice can help.

Since your Frenchie is having other issues such as trouble breathing and lethargy, it may be a good idea to contact your vet for advice. Minor digestive upset can cause lethargy due to the energy expended in vomiting, however prolonged symptoms usually indicate something more serious is going on.

Bulldogs are one breed that are prone to bloat (though any breed of dog can be affected), a serious medical emergency. Signs of bloat can include a suddenly painful and bloated abdomen, signs of distress such as heavy panting, whining, or trouble breathing, pale gums and tongue, vomiting and diarrhea, or attempting to vomit or defecate without success. If you suspect your dog may be experiencing bloat please contact your vet or emergency clinic immediately.

Q. My cat starts to breathe fast for no reason when he starts to go to sleep. Is there a way to figure out what’s wrong?
ANSWER : A. If your cat has been having breathing problems, it is best to contact your local veterinarian for a wellness exam. Your vet can help determine if there is a cause to the changes in breathing, and if there is a medical reason for it. Even if there isn’t a cause found, knowing that there isn’t something more serious happening can provide some peace of mind.

If your cat begins to have trouble breathing, however, such as open-mouthed panting, or blue tongue or gums, it can indicate a serious medical emergency that should be brought to the attention of your vet or ER clinic immediately.
