A. If she has been straining to pass feces or urine then you need to see your vet as soon as possible. Im assuming she has been urinating and it is just feces that she hasn’t passed. If she is well in herself monitor her and see how she is in the morning. If she still hasn’t passed anything by lunchtime tomorrow then give your vet a call. It can sometimes be caused by a diet change.

How to Identify Common Pet Problems ?

THe most common reasons a puppy may refuse to eat include: stress and anxiety, environmental issues, digestive issues, illnesses, teething pain, and food preferences. If your puppy refuses to eat, it`s important to consult with a veterinarian who can diagnose and provide appropriate treatment.
Growth and development begins to slow around the 10-12 month mark. However, mental and emotional development continues long after your puppy`s first birthday. Your pup still needs you there to provide guidance, reward good behavior, facilitate opportunities for socialization, and provide physical and mental enrichment.
Your dog may not eat for many reasons: if they`re in pain; are feeling anxious or stressed; if they`re unwell; feel nauseous; if they have side effects from medication; and sometimes simply because they don`t like the food you`ve given them.
Infections, illnesses, and pain can make your dog tired, listless and uninterested in food. When these symptoms continue for more than 24 hours, they could indicate the presence of a health issue that requires a visit to our veterinary hospital in Diamond Bar.
Very young puppies need to eat a high-quality puppy food diet approximately 3 to 4 times per day. The frequency of feeding puppies goes down to 3 times per day at around 3 to 6 months of age, and 2 times per day at around 6 to 12 months.
While some puppies are more laid back than others, lethargy (low energy) is sometimes indicative of a health issue. Anything from an infection to pain to obesity can cause lethargy. If your puppy seems unusually lethargic, call your veterinarian to find out the root cause.
When your puppy is 10 months to 1 year old, she is considered a teenager. She is beginning to think of herself as independent. The world is hers to explore. She can go on longer walks and even enjoy off-leash time.
Stage 5: Adolescence (6 – 18 months) This can be the most difficult time during a puppy`s development – adolescence. Your cute little puppy is becoming a teenager and will start producing hormones which may result in changes in behaviour.
Depressed dogs may show symptoms such as a lack of interest in activities, loss of appetite, increased irritability, and unusually clingy or needy behavior. You can help improve your dog`s mood by giving them plenty of exercise, playtime, and mental stimulation.
Look at your pup`s body language for cues

If your pup runs to their dish, takes a sniff of their food and begins eating right away, chances are they like it! If your pup takes a sniff and turns away, that is probably a good sign that they aren`t particularly interested in that dish.

Signs Your Dog Feels Neglected

There are some tell-tale signs. Dogs often engage in destructive behavior when feeling neglected, like excessive digging, chewing and scratching. Another way they might express their feelings of frustration are through barking and howling fits, particularly at night.

Why does my dog eat like he`s starving? Many conditions can trigger increased appetite in dogs. A dog may have learned the behavior because they were not properly fed or became anxious about food. Or, they may have developed a metabolic condition or infection or have parasites.
“Growth” foods necessary at the puppy stage have higher protein levels and calorie counts to meet your pup`s developmental needs. But once your pup is six to 12 months old those needs change. That`s usually when your puppy is nearing his adult height and can transition to adult food.
6–12 months: Begin feeding twice daily. Spaying or neutering lowers energy requirements slightly; after the procedure, switch from nutrient-rich puppy food to adult maintenance food. Small breeds can make the switch at 7 to 9 months; bigger breeds at 12, 13, even 14 months.
Most puppies can switch to two meals a day when they are between six and 12 months old and should continue eating that way for the rest of their lives. But, while most dogs do well on a two-meal-a-day schedule, adding a third meal can also be a good option.
In fact, when it comes to continuous puppy walking a good rule of thumb is that puppies should have no more than 5 minutes of exercise for each month of age, two times a day. So a five-month-old puppy would have no more than 25 minutes of walking twice a day – and this should be decreased in larger breeds.
Your puppy`s exercise needs will change as she grows. When your puppy is very young, veterinarians recommend keeping exercise limited to short walks and multiple play sessions throughout the day, with plenty of time for naps.
After six months, dogs can usually hold it for up to six hours. However, even adult dogs shouldn`t be home alone for much longer than six to eight hours without a chance for a bathroom break.
Most puppies start to calm down as they approach their maturity age, which is usually around 12 months, but for larger breeds it can be more likely to occur between 18 months and 2 years.
All dogs are different but, usually, adolescence begins with puberty at around 6 months of age and continues until social maturity at about 18 months of age, although it does often get a little bit easier when they reach about 1 year old.
As puppies age, they grow more independent, and by 6-12 months you may notice your once obedient pup is developing some unwanted behaviors. Don`t worry, some simple training tips will help you both get through these growing pains.
Research Shows Your Dog Can Hear When You`re Happy or Sad. Dogs` ability to communicate with humans is unlike any other species in the animal kingdom. They can sense our emotions, read our facial expressions, and even follow our pointing gestures.
Your dog may be isolating himself because of a mental or physical condition, the reason of which could vary. Anxieties and fears are commonly seen in dogs, and can develop due to a number of reasons, such as poor socialization or trauma.
Some dogs become bored with the smell, flavor, and texture of their food. Change out one ingredient, such as swapping any chicken-based food for fish or lamb. You can also add fresh ingredients to the dog`s kibble. Both steps may awaken those sensitive noses and make an old dish more exciting.

Q. My 10 month old pup doesn’t use the “facilities” as much as she should be. She didn’t go this morning, hasn’t since. Eats/drinks regularly.
ANSWER : A. If she has been straining to pass feces or urine then you need to see your vet as soon as possible. Im assuming she has been urinating and it is just feces that she hasn’t passed. If she is well in herself monitor her and see how she is in the morning. If she still hasn’t passed anything by lunchtime tomorrow then give your vet a call. It can sometimes be caused by a diet change.

Q. My Bulldog puppy growls, barks and even tries to bite me when I say “no” to him. What can I do?
ANSWER : A. First, avoid scolding him and acting aggressively towards him if you don’t want him to be acting aggressively towards you. There are other methods you can use to communicate to your dog that you don’t want him to continue doing what he is doing. I recommend you stop telling him “no”, scolding him, or raising your voice at him. Everything coming from you should be 100% positive and 100% calm.

Try to figure out ways to clearly communicate what you want to your dog. If you want your dog to leave something or someone alone, I strongly suggest teaching your dog commands like “leave it”. Here is a link to a video in which I explain how to do it:

www.youtube.com/watch?v=R1TS5nA7z5Q

Another thing I suggest you use is a no-reward marker. This clearly communicates when your dog has done something wrong. No-reward markers have to be introduced during your training sessions. You should be doing at least three training sessions per day, that are something like 3-10 minutes long (working on different things each training session). If you are teaching your dog something BRAND NEW, do not use the no-reward marker, as you do not want to discourage your dog from performing behaviors for you. Use the no-reward marker for known behaviors only. Here is another helpful video about this:

www.youtube.com/watch?v=sdU5a6fXKlg

Lure each new behavior (as shown in the video) using high value treats. Let’s say you’re working on “down” which is a behavior your dog knows fairly well. Present the treat to your dog. Ask your dog to “down” (only ask once). If he does not go “down” immediately, say, “uh-oh” or “eh-eh” in a gentle tone, and then place the treat behind your back. This communicates to your dog that they did something to make the treat go away.

After you place the treat behind your back to show your pup “that was wrong” you need to communicate to your pup “let’s try again” by getting your pup to walk around for a second, and then start the behavior all over again. If your puppy is very young, chances are you haven’t taught him a solid “down” behavior yet. So, as I said, do not use this method until you have lured each new behavior as shown in the video.

This is the order in which you should teach behaviors: Lure using a high value treat as shown in the video. After a few successful food lures, lure with an empty hand. If the pup is successful with the empty hand lure, reward with lots of treats. If the pup is unsuccessful, then go back to food-luring a couple more times. After a few successful empty-hand lures, you can begin to add the cue. Say “sit”, then lure with an empty hand, and then reward. Once your pup understands the cue, begin to work on the no-reward marker.

Q. My three month puppy is teething and she’s biting everything. What can I do?
ANSWER : A. As you know, this is a normal issue to have with a 3 month old puppy. Be sure that you are never scolding your pup for biting/nipping/teething. This is so natural and normal for them, scolding gives very mixed messages. There are a few things you can do to help teach your pup that nipping on you is inappropriate without the use of scolding.

First off, you should have a toy that YOU own. This toy should be brand new. It should be something like a SOFT braided rope toy. Never allow your pup to play with this toy without you. Never leave this toy on the ground for your pup to play with. Never allow your pup to “”win”” tug games with this toy. This toy disappears when YOU are finished playing with it. This toy is hidden from your pups sight whenever you are finished playing with it. After about a week of keeping this toy hidden from your pup, and only bringing it out when YOU are engaging your puppy in play, you can THEN begin to use it to redirect your pups attention when she nips.

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. Husband shamed dog for having an accident inside, and now she won’t poop when he takes her out. Can we fix this? He realizes he erred
ANSWER : A. Good on your husband for realizing that scolding is not the way to potty train! Hopefully these tips can help both him and your pup get back on the right track and make pottying outside successful.

If your dog is still a puppy, that is good news as you may be able to more easily time your potty outings with your dog’s schedule. Even if your dog is older, this schedule may help. Dogs generally have to go potty about 15 minutes after eating, drinking, waking up or playing. Knowing this, get your husband to start taking out your puppy at these key times, so puppy gets used to going out with him, and the urge to potty may be higher than any fear to go. If the potty is successful, have your husband reward the dog with a favorite treat! For bowel movements, dogs may take a little more time, and you may have to stand outside for a while (sometimes even 10 minutes) to give your dog a chance to go. If she doesn’t go, take her back inside and play some, then try again in about 15 minutes. Again, a success equals a treat which most dogs will like right away!

For any indoor potty accidents that occurred, an enzymatic cleaner is great for cleaning up urine and stool. Not only does it remove the stain and smell, but it breaks down the enzymes in the urine and stool your dog can smell, which may deter her from going potty there again.

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 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. 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).
