How to Identify Common Pet Problems ?

Pain is the main reason that dogs hate nail trims. If your dog has ever been cut too close, even once, he will remember it. Nature provides pain as a protection and if something hurts, an animal must learn to avoid, and even fight it. This is a survival instinct.
Desensitization to Nail Clipping

Buy a pair of nail clippers and show them to your dog while presenting a treat. If necessary, you can also simply place the nail clippers on the ground where your dog can see them and provide a lot of positive reinforcement as they get sniffed.

There are many owners who take their dogs to the groomers for trimming, for fear of hurting their pooch or getting it wrong. Nail neglect can lead to pain and health risks for your four-legged friend, including a splayed foot, reduced traction, pain when walking, and worse, deformed feet and injuries.
Unless there is a medical reason not to sedate your dog, your vet should be able to do a sedated trim. Being sedated should make the nail trim process less traumatic for your pup.
It is therefore important to keep your dog`s claws well trimmed at the correct length. If they get too long it can put pain and pressure on the toes and paws, which will ultimately put strain on the legs. Long claws are also prone to splitting and infection.
Unless your dog is incredibly active and takes daily long walks on sidewalks or hard surfaces that fill the role of a nail file, it`s likely that their nails will need trimming a few times a month.
The nail will bleed and your dog will cry; it`s just as painful as it is for us when one of our nails breaks into the quick. It`s harder to see the quick in black nails, but if you look at the underside you can make it out sometimes.
They`ll infuse the space with calming pheromones in the air or essential oils through a diffuser. Perhaps they`ll use certain shampoos with soothing ingredients, like lavender. If and when a vet writes a prescription of sedatives for a dog`s grooming session, then the groomer can use those to keep a dog still.
Acepromazine. Acepromazine causes sedation. It`s commonly given as an injection as part of anesthesia (one of a combination of drugs) for surgery. The drug may also be sent home as an oral medication and given to a dog 20-60 minutes before events like grooming, a vet visit, or car travel.
Generally, your dog`s nails shouldn`t touch the ground when he`s standing upright on all four feet. There is no hard and fast rule as to how far from the floor those nails should be; it varies from dog to dog. If the nails click on the floor, they are usually too long.
Clip only the tip of the nail, straight across. Include the dewclaws, located on the inner side of the paw. Avoid clipping past the curve of the nail or you risk hitting what is called the quick (the pink area of the nail that contains the blood vessels). A nick there is painful and will bleed.
Nails soften if soaked in water. Try trimming nails after bathtime or let your dog stand in a few inches of water in the bathtub for about 15 minutes.
Don`t force your pup – small steps, patience, and practice are critical. Gauge your dog`s stress threshold and don`t force him past his comfort level. You might need to start with getting him comfortable with touching his paw, progress to touching his paw with the scissors, and only weeks later start trimming.
Dogs who spend a lot of time outdoors walking on hard surfaces will have nails that are shorter and blunter than dogs who spend the majority of their days indoors and do not take long walks on hard surfaces. Dogs who don`t walk or run on hard surfaces will need their nails trimmed more often.
Salon Grooming Helps Alleviate Doggie Anxiety

They need mental stimulation and plenty of exercise to be happy.

Dogs are happier after grooming due to the many health benefits and overall cleanliness that it provides. Grooming also provides an opportunity to be social with other dogs and groomers. Although some dogs may feel down after grooming, this quickly goes away and they truly appreciate the benefits of grooming.
The groomer will look for ways to gain their target`s trust, often with gifts or promises. Eventually they`ll start to ask for something in return, and this eventually leads to abuse. Because groomers work to befriend their victims, some organisations refer to it as “mate crime”.
This could be due to various reasons- anxiety, fear, confusion, or bad previous experiences while being groomed. If your dog had a bad previous experience with groomers, they may become extra defensive the next time they enter a grooming salon. The dog could bite anyone who approaches or tries to touch it.
Dogs need their nails clipped on a regular basis, approximately every 3-4 weeks; however, it is common for owners to wait too long in between trimmings which can lead to a number of health issues for the animal. For cats, a routine claw trimming every 10-14 days will keep your pet healthy.
If you dog has dark nails trim very thin cuttings off the end, as it`s easy to accidentally damage the `quick` or soft part of the nail. If you see a black dot in the centre of his nail, you have reached the quick and should stop cutting right away.
At the center of every dog nail is a bundle of nerves and blood vessels called a quick. Cutting this quick, or even applying pressure to the area around it, can cause your dog immense pain. Some breeds, such as Shiba Inus, pugs, shepherds, labs, and bully breeds, seem to have exceptionally sensitive quicks.

the most relevant questions and answers related to your specific issue

Q. My dog has a split nail, what should I do?
ANSWER : A. Split or torn nails are very common in dogs, and treatment depends on the level of the tear. If the nail is split above the quik (blood supply to the nail) then it can be safely trimmed back and the torn part removed. You can find the quik in a dog’s nails by looking for a red or pink line in light colored nails, or a darker groove on the underside of dark colored nails.

If the tear is behind the quik or the nail is bleeding, stopping the bleeding with styptic powder or starches such as corn or rice starch can help. It is then best to bring your dog into your local vet to have the nail safely trimmed back. This may require anesthesia or sedation depending on the size of the tear to make the experience less painful for your dog. Your vet may also recommend antibiotics if the tear is large to prevent infection from taking hold until the nail can heal.

Once the torn part of the nail is removed, the nail should be able to begin growing back as normal. Regular nail trims to keep nails short and in shape can also help to prevent tears and splits in the future.

ANSWER : A. Lots of pets don’t like having their nails cut, mine included! Often they behave better for other people so book it in with a groomer or your vet to do.

Q. I have tried everything to cut my dogs nails and it is impossible. Dremel and clippers. They are causing her a lot of pain. What should I do?
ANSWER : A. Nail trimming should not be painful unless you are getting the quicks. Try clipping or grinding the very smallest bit of nail that you can for a while, but you will have to do it every week so the nails don’t grow too long. Try having someone let her lick a cup of ice cream while you work–this may help to distract her. Get her used to your handling her feet often when you are not doing her nails.

Q. I found my cat’s nail on my bed today… Im worried and I dont know what to do … Can you please help me?
ANSWER : A. A cat’s nail has layers, almost like an onion. You may have only found an outer layer that was shed and this is normal. If, however, the entire nail fell off or was torn off….you should take her to the vet for an exam. This can be painful and an infection can occur. If the whole nail is gone, you will likely see a red and irritated tissue. If only the outer layer shed, the nail will appear normal and no treatment is needed. Check each toe and call your vet if needed.

Q. I just noticed my dog has a vertical black line that runs down through the middle of some of her nails. Is there something I should be worrying about?
ANSWER : A. It’s nothing to worry about. If it is deep inside the nail it is the quilt, a little blood vessel. When you clip your dogs nails it must be 1-2mm below this otherwise it will bleed a lot. If it is on the outside of the nail it is just the pigment if the nail and perfectly normal.

Q. When Yoz Start Holding The Kittens. When Can They come Out Of Thr Birthing area?
ANSWER : A. As long as you wash your hands, and make sure you are very clean and not sick, you can interact with the baby kittens right away. You want to be handling them often so they get used to people handling them! Do not allow them out of the birthing area until they are at least a month old I would say. You want to get them checked out by vet, but make sure you bring them in a cage. They should at least have had their first vet check-up before being allowed out of the birthing area to roam around your CLEANED home. Clean your home very well, with products like SIMPLE GREEN so they are safe to roam. Do not allow them outside, and do not allow them to interact with other animals until they have all had their shots. When people come over to hold/interact with them, make sure they wash up very well, and ask about the pets they have at home.. make sure they don’t have any sick pets, or any pets who have ever had PARVO.

Good luck with the babies!!

Q. I have a 1yr old male 38 lb Labradoodle and my gf just brought a month old kitten home. Can they interact? If not, for how long?
ANSWER : A. Interactions whenever a new pet is brought into the house should start off slow, then can be increased in time. The best steps when introducing a new cat is to allow your cat or kitten to have a room in the house all to him or herself. Allow your dog to sniff under the door to get used to the kitten’s scent, and even show your dog articles such as bedding the cat has slept on. After a few days, an introduction with your dog on leash, or a barrier such as a gate where both pets can look at each other but not see each other is best. This will allow each to get used to seeing the other without the ability to jump, bite or scratch the other. Once the two are used to this, then a face to face interaction can begin. If at any time a fight or scuffle breaks out, separate the two pets and try again at a later time. The amount of time this introduction takes can vary depending on how the two react to each other.

Until your kitten is older, or you are sure both are fine together, do not leave the two pets together unattended. Even a well-meaning and playful dog can accidentally break a leg of a kitten or worse without meaning to! A safe room for your kitten to be in while you are away, or a barrier to allow your kitten to escape to safety if needed will help until both are big enough to play alone safely.
