A. Some dogs will eat at every opportunity. I would recommend making sure that you have treated for worms with a good quality worm product from your vet as the over the counter ones are not as effective. Make sure that you are feeding a good quality, complete and balanced dog food and that you are feeding just the recommended daily amounts as you don’t want him becoming overweight.

How to Identify Common Pet Problems ?

Dogs can be hungry because: it`s genetic, they`ve exercised a lot, they have health issues (such as diabetes or worms), it`s a side-effect of medication, they`re stressed, they`re bored or because they`re not getting enough of the right type of food.
In short: No. “In heat,” or estrus specifically refers to the time in the female dog`s reproductive cycle where she becomes receptive to mating with males. According to the American Kennel Club, male dogs don`t go into heat; instead, they`re capable of mating year-round once they become fertile at about 6 months old.
When they are above three months old, it is recommended to feed them three to four meals a day. Adult chihuahuas (12 months and older) can be fed two to three meals a day. Learn more about when to switch to two meals a day for your puppy.
This ideal food then needs to be portioned correctly and given within three meals a day that has been appropriately spaced out. An adult Chihuahua should eat between 4-10oz a day, depending on their ideal body weight.
There`s no clear-cut cause for why a dog might be obsessed with eating. It could stem from a psychological issue, such as stress or learned behavior, or a medical issue, such as not getting the right nutrients or an underlying health condition.
Dr. Jules Benson, VP of Veterinary Services at Petplan Pet Insurance says, “typically, the insatiable hunger can be attributed to canine biology, but it also can be a warning sign for a medical issue such as diabetes or Cushing`s disease.”
Give your male dog lots of exercise and stimulating playtime to reduce his energy and keep him distracted. Mask a female dog`s scent by spraying her tail with menthol spray. Or, put dog diapers on her. Keep your dog as far away from the female as possible.
The canine estrous (reproductive) cycle is made up of 4 different stages. These are proestrus, estrus, diestrus, and anestrus.
The Chihuahua does require regular bathing and brushing. This self-confident little dog can be bathed as frequently as every week up to no longer than 6 weeks, depending on lifestyle and activity level. Somewhere in between is a happy medium.
The best diet for a Chihuahua is balanced and appropriate for their life stage and energy needs. This typically includes a combination of high-quality protein, healthy fats, vitamins, minerals, and fibre from vegetables and berries.
How Much Sleep Does a Chihuahua Need? Chihuahuas are known for sleeping most of the time, and while the majority of breeds are fine with 12 to 14 hours of sleep every day, Chihuahuas usually sleep from 14 up to 18 hours a day.
When Do Chihuahuas Stop Growing? Chihuahuas usually reach their adult weight between 9-12 months of age. The average weight of a Chihuahua is between 2.5-4.5 lbs and 5-8 inches tall but this can vary between dogs. In general, standard Chihuahuas shouldn`t be over 6lbs in weight.
Simply put, dogs beg for food because they like food. Food smells and tastes good, especially human food that they don`t normally get. Dogs are driven primarily by their sense of smell. Naturally, they want to check out what`s on our plate when it smells like something they should try to get in their mouth.
To do this, try your best to ignore them completely whenever they beg. This means not looking at them or talking to them, even to tell them to stop begging, until you`ve finished eating. A slight glance in their direction can encourage them to keep trying as they`re getting a response from you.
Licking is a natural and instinctive behaviour to dogs. For them it`s a way of grooming, bonding, and expressing themselves. Your dog may lick you to say they love you, to get your attention, to help soothe themselves if they`re stressed, to show empathy or because you taste good to them!
Look at your dog if their waist is extremely exaggerated instead of a gradual slope your dog might be underfed. If you can see or feel the ribs and they don`t seem to have any fat on them your dog is probably underfed. If your dog is losing patches of hair there may be an issue with the nutrition.
The onset of puberty will be most recognizable in your male dog. He`ll begin lifting his leg to mark territory and mounting other dogs, humans, and even furniture. It`s not unusual to discover a puddle of urine, left by a formerly housebroken adolescent dog.
While frequency varies according to breed and individual dogs, usually dogs go into heat about twice a year or every six months. Each estrus period lasts about 18 days. Male dogs will be attracted to a female dog for the full 18 days, but the female dog will only be receptive to males for about half that time.
Research shows that dogs of all ages, shapes, and sizes experience mood swings from time to time. Mood swings happen for many reasons, and they look different ways depending on the stimulus and your dog`s temperament.
Not only are they not fertile, but their reproductive organs won`t open for penetration unless they are in heat so they can`t even engage in intercourse. If you discover that your female dog has engaged in intercourse, chances are that her heat symptoms were minimal or silent, so you did not realize she was in heat.
To get to the heart of your question, male dogs have excellent senses of smell and can sense an intact female in heat up to 3 miles away. Dogs have geographic territories, and they can generally detect any intact females within those boundaries.
According to The Kennel Club, these tiny dogs only need up to 30 minutes a day of exercise. A nice walk around the park will give those little legs the workout Chihuahuas need to stay happy and healthy. She is very agile and fit for such a small dog. Two short walks a day can be enough.
But a good rule of thumb is that dogs should poop at least once a day. Some may poop up to five times, and others in between.
Wet dog food can be a great option for Chihuahuas, as it is often more nutrient-rich and palatable than dry food. However, it is important to choose a wet food that is specifically designed for small breeds like the Chihuahua, as regular wet foods can be too high in calories.

Q. Why does my dog eat grass?
ANSWER : A. As another user mentioned, dogs can eat grass when they want to vomit. Sometimes, when a dog has an upset tummy, they will eat grass. If you notice your dog eating grass frantically, you can assume vomiting will shortly follow. Grass does not digest and pass normally. If your dog eats too much grass, it can cause serious issues with pooping. Your dogs poop can end up all tangled inside of her, and it can need veterinary assistance to remove it. The same goes for celery, so avoid feeding celery to your dog.

The other day my boyfriend accidentally left the laundry room door open where we were keeping the trash that was filled with cooked chicken bones. She ate one of the chicken bones lightning fast. We had to induce vomiting by feeding her some hydrogen peroxide. After we had fed her the peroxide, she immediately began frantically eating grass because her tummy was upset.

If there is something lacking in your dogs diet, it could be that your dog is eating grass to make up for it. I am sure that my dogs diet is extremely well balanced (I do not only feed her an air-dried raw food-type diet (Ziwipeak), but a wide variety of safe, healthy foods), so when she eats grass, I know that it is because she has an upset tummy.

That is why I think it is important making sure your dog has a very well balanced diet. If your dog is on a low quality kibble, your dog may be trying to let you know by eating grass (or eating poop).

Q. My 3 month puppy eats his own poop and is also biting what can I do to prevent this
ANSWER : A. When it comes to poop eating, you want to consider a few things. First off, what is his diet like? Maybe something is lacking in his diet that is causing him to want to eat his own poop. This is the most common reason why dogs eat THEIR OWN poop. Try a higher quality kibble like Taste of the Wild, Ziwipeak, Orijen.. and try feeding three meals per day, instead of the more common two meals per day. Remember to gradually switch his kibble. Add a little bit of the new kibble and reduce the old kibble very slowly.. little by little every couple of days until the bowl is mostly new kibble! You should also be cleaning up his poops IMMEDIATELY after he does them.. I mean like, you have a bag in your hand, and you are low enough to scoop it up RIGHT when he finished so he doesn’t have a chance to eat his poop.

When it comes to nipping there are a few things you can do. First, you should yelp as soon as the teeth touch your skin, stand up, cross your arms, and ignore the puppy until he is ignoring you. Once he is off doing his own thing, swoop down and calmly reward him by playing with him WITH A TOY so he doesn’t nip your hands. Whenever you pet him, or interact with him, you should always have a toy on-hand so you can give it to him. This toy should be a soft braided rope toy that YOU own. This means, your puppy is never allowed to have this toy on the floor, and your pup can never “win” tug games with this toy. This is YOUR toy that disappears when you’re finished playing, and reappears when you want to play. If you keep this up, in a weeks time, your puppy will be so excited to see that toy, that as soon as you bring it out, he stops nipping you because he wants to play with the toy. Another thing you can do is have two bags of toys. Bag#1 is full of chew toys/soft toys/squeaky toys/etc. After one week, Bag#1 disappears and out comes Bag#2. Bag#2 has the same types of toys as Bag#1, and it only stays out for one week. This keeps the toys feeling like new to your pup!

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. My dog doesn’t eat, what should I do?
ANSWER : A. If this is a puppy, see a veterinarian immediately. Puppies should want to eat. Common causes for anorexia in puppies include viruses (parvo is a big one), parasitism, and foreign bodies. They need immediate care – go to an emergency vet if yours isn’t open. Puppies can get low blood sugar and dehydration very quickly.

If this is an adult dog and you observe other concerning signs, such as diarrhea or decreased energy, you should see a veterinarian.

If the dog seems otherwise bright and stable, try offering different types of food: wet food, canned tripe, or cooked chicken and rice. Some dogs will go for canned baby food: chicken, turkey, or beef as the main ingredient. Make sure there are no garlic or onions in the ingredients!

Causes of anorexia in adult dogs can range from less serious to severe. Younger dogs are more likely to get into trouble- they tend to eat things they shouldn’t, and can get foreign bodies from eating things like socks, or stomach upset from getting in the trash. Any dog may stop eating due to stress, or just being a picky eater. Middle aged dogs can stop eating when they’re stressed and also have Addison’s disease, which can be fatal. Older dogs tend to stop eating when they develop cancer or renal disease.

There is no one-size-fits-all recipe to know when the right time is to take your dog to the vet. The moral of this story is, if it’s not getting better, your pup feels bad, or you’re worried – go see the vet!

Q. My 20 month Cavalier doesn’t eat unless I let him eat from my finger, then he eats. Sometimes he will only eat once a day and leave his food.
ANSWER : A. It is possible that your dog is just not satisfied with his current food, or may be a picky eater. There are several things you can try to encourage your dog to eat.

The first step is to remove any additional treats or people food that may be more enticing to your dog than his own meal. If you feel you must give him some form of treat, be sure to place them directly in his food bowl and mixed with his regular diet. This allows him to get some snacks while also “forcing” him to try out his current meal to get the reward.

Enticing your dog to try his food by adding a pet-safe gravy or even a few treats of plain boiled chicken mixed in can help. Be sure to mix the foods thoroughly so he must explore his own food before getting the treat.

Some small breed dogs may also have a hard time with certain bowls and their collars. If there is a metal name tag on the collar and a metal bowl, the clinking sound can sometimes scare off dogs and make them not want to eat from their bowl. Using a bowl of a different material, or removing the collar prior to a meal may help with this issue.

Your dog may also just not be into his current food and may like another variety better. You can try a new variety by gradually switching over a period of 7-9 days, slowly adding in more new food and removing old until it is switched. This change may encourage him to try out meals again, and the slow changeover will allow his body to adjust to the new diet without digestive upset.

Q. My 2 months old rottweiler puppy isn’t eating properly. Shes only eating shredded or minced chicken but adding any thing means she won’t eat.
ANSWER : A. This is not a nutritionally adequate diet for your puppy. She needs to be eating a good quality puppy food. Put the proper amount in her bowl and put it down without any fuss. Leave it for fifteen minutes. After that, if she has not eaten, pick it up–again without fuss–and do not give her anything else to eat until her next scheduled mealtime, not even treats. When she is due to eat again, repeat the process. This may take quite a few days to resolve, as she will try to hold out for the chicken. Do not give in! Remember that you are not starving her. The food is there, but she is choosing not to eat. When she realizes that this is all she is going to get, she will begin to eat and your problem will be solved.

Q. I have a male Chihuahua who’s about a month and all he wants to do is eat. Is this normal?
ANSWER : A. Some dogs will eat at every opportunity. I would recommend making sure that you have treated for worms with a good quality worm product from your vet as the over the counter ones are not as effective. Make sure that you are feeding a good quality, complete and balanced dog food and that you are feeding just the recommended daily amounts as you don’t want him becoming overweight.

Q. My cat is one year old. He has diarrhea, not eating last for one day. This problem is too with my other 2 cats and one is died.
ANSWER : A. His not eating is the most concerning for me. They cannot go more than a few days without eating or they risk liver damage. Your cat needs to be seen by your vet for an exam and bloodwork to determine the cause for your cat’s loss of appetite. Based on the findings, your vet will be able to give you a clearer picture of what is going on with your cat and be able to offer you treatment options.

Try enticing your pet to eat with beef or chicken baby food that does not contain onion or garlic powder. Onion and garlic causes anemia. Warm it in the microwave for a few seconds. Stir it with your finger first to make sure there are no hot spots and that it isn’t too hot. This makes it more aromatic and appealing to your pet. Wetting dry food or mixing wet food with low sodium chicken broth, also warmed, might entice your pet to eat. Some cats like to be petted while they eat, some want to be left alone. You’ll know your cat’s habits and be able to act accordingly.
