Experienced and professional animal trainer provide their insights in answering this question :
A. It’s all about management. Do not allow the 7yo’s to interact with your 14yo unsupervised. You should be there each time they interact so you can redirect the 14yo’s attention onto some toys, or onto some treats when the 7yo’s are around. It sounds like you need to help your 14yo make positive associations with being around the younger pups. You should be trying to feed him treats each time he interacts with them, and doesn’t snap at them. Pet and praise him each time he is around them, or any time they are near. As I said, keep the separated when you cannot supervise their interactions because if you aren’t around when he is snapping at them, you could end up with a fight on your hands.

It could also be that they spend too much time together. Imagine spending 100% of your time with somebody, day in and out, doing everything together… including going to the bathroom.. that might bother anybody. I think you should give them more time apart from each other. Take them all on separate walks, separate them to play with them individually, separate them when you take them to potty, separate feeding times in separate rooms, etc. This can help alleviate the stress your older dog is feeling due to living closely with other dogs. You should always be giving individual activities in a houseful of dogs anyway.. when you expect them to get along 100% of the time, that’s when you find trouble.

How to Identify Common Pet Problems ?

Dogs aren`t programmed to take care of youngsters. Your dog may want to go away from the puppy or may growl or even snap to tell the puppy to go away. However, if your older dog uses his teeth on the new puppy, that is not normal, and it may be time to consult with a veterinary behaviorist.
Go to the Vet

One of the reasons a dog can get aggressive is due to illness, injury, or confusion, regardless of their age. As a dog ages, it`s common to have some health concerns. Something like dental pain, arthritis, or vision and hearing loss can trigger aggression in a senior dog.

They snap because they feel threatened. Most dogs snap at adults and children because they feel threatened by how they are approached. So how can you, as a responsible dog owner, stop this aggressive behavior and keep it from worsening? Start by understanding why your dog may feel threatened.
For example, medical conditions that lead to pain and loss of mobility may cause a dog to become aggressive when approached. Aging dogs often experience a change in their hearing and may bark more often, possibly startling the younger dog and triggering an aggressive response.
If your previously placid pooch suddenly begins growling, snapping, or biting, it may be due to a disease or illness that needs diagnosis and treatment. Pain caused by an injury or illness can lead to discomfort, stress, and aggression in older dogs.
Many older dogs will be upset, jealous, or even angry with a new puppy, especially if the older dog has been an only dog. It`s going to be important to make sure the older dog gets lots (more than normal) of attention to alleviate potential hurt feelings.
Is training an aggressive dog possible? Yes. Aggression in dogs, whether it be toward a dog`s owner or other dogs, is a serious behavior that should be adjusted with the help of a professional dog trainer.
In addition to being less active, many dogs at this age begin to develop digestive issues, kidney problems and other conditions that can benefit from diet modification. Only your veterinarian can accurately assess your dog`s needs.
After 14 years, your doggo is practically your other half. In fact, they probably know you better than you know yourself! Their days of jumping and running may be over, but they still have plenty of love to give and belly rubs to enjoy. At this point in their life, comfort is priority.
Dogs have an extremely sensitive sense of smell. Dogs can average a 10,000-100,000 times stronger sense of smell than humans. Therefore, something in a person`s scent may trigger your dog to growl, and it will not even register with you. Dogs also make associations by how things smell.
A multitude of factors can contribute to an increase in a dog`s aggressive behavior. Medical conditions that affect your dog`s appetite, mobility, cognition, senses or hormones can lead to increased aggression, as can conditions that cause him pain or irritability.
Social aggression usually develops in dogs between one to three years of age. It`s important to realize that the complexities involved in social aggression are poorly understood and hotly debated by behavior experts.
Clicker training is particularly effective for teaching calm behavior, since the clicker lets you catch that moment of quiet and reward it. Have treats with you or stashed around the house, so you can catch and reward your dog for sitting, lying down, resting on his mat, or other calm behaviors.
A dog`s aggression can lead to a bad outcome if your dog bites someone. The good news is that a growl or snap is your dog`s way of communicating a waning—and your dog is choosing to warn you instead of biting.
Dogs in the same household can become aggressive toward each other for a variety of different reasons. Aggression may be dominance-related, territorial, possessive, or caused by fear/anxiety. Some dogs have “alliance aggression”.
A Calming Influence

A calm, sensible adult dog can help to show a new puppy that your home is a comfortable, relaxing place to live in. And they can also help soothe any anxieties over their new surroundings.

It can take up to one month for an old dog and new dog to really settle in and accept each other`s position in the pack. If you want a second dog, you need to be ready to commit to this process and not panic.
It`s not unusual for the adult dog to have opinions on the puppy`s learning processes. If the puppy is disrespectful, perhaps trying to steal the dog`s reward, the adult dog may growl, bark, nip or otherwise chastise the puppy. The puppy may cry, back away, or roll over to bare his belly.
“My dog is aggressive towards me but not my husband” is surprisingly a common comment I hear from clients. The reason why is either due to 1) Lack Of Early Socialization 2) Trauma or 3) Trust.
While male dogs who are neutered do experience an increase in aggressive behaviors right after the procedure, neutering can make them much less aggressive over time. In fact, neutering has bee proven to create a much happier and calmer male dog over time.
Signs To Look For

Some common signs that it may be time to put your pup down include the inability or refusal to eat or drink, labored breathing, an inability to get up for potty times without help, urinary or fecal incontinence, and immobility. Essentially, this can come down to your dog`s quality of life.

Take a new approach to exercise

“In fact,” she says, “I would encourage shorter, but more frequent, exercises over a long exercise duration for most senior dogs—for example, a 10-15-minute walk in the morning, a 10-minute walk in the afternoon, and a 20-30-minute walk in the evening.

Even if your dog is considered senior, you`ll still want to give them at least 30 minutes of daily exercise. Because of their age, exercise might need to become shorter but it`s still necessary to make sure they`re getting the required stimulation. Choose low-impact activities. Go on walks, not runs.
Do not try to punish your Yorkie. While it seems intuitive to humans to punish bad behavior, negative attention is an ineffective deterrent for dogs. Giving your dog attention in the form of a scolding is actually rewarding the dog with attention in its eyes.

Q. Does an indoor cat need to be vaccinated every year?
ANSWER : A. In practice, I recommend a feline combo vaccine every year, but will generally start administering every 3 years once they have had their kitten vaccines and 2 additional yearly vaccines. Rabies, is required yearly by law, and if kept up to date can be good for up to three years also. Based on the age of your cat I would give a yearly feline combo and rabies, and then boost the combo again next year.

Q. Are Yorkie Poos alright to be left alone some of the day and are they easily house trained
ANSWER : A. They are not very easily house trained, no. Yorkie’s have small bladders, and tend to drink more than other small breed dogs. Yorkie’s need to be on a very strict pottying schedule. When they’re puppies, they should be brought outside every 30 minutes when they’re out of their crates, and when they are in their crates the “rule of thumb” is one hour per month of age, plus one (until they ABSOLUTELY HAVE TO potty). Crate training is extremely important when it comes to raising a puppy, especially one who has notorious issues with potty training.

I could go over a crate training exercise for you so you can start crate training right away. Crate training is a very SLOW, careful, and positive process. It needs to be handled very delicately to ensure the puppy has a positive experience.

Of course dogs are alright to be left alone some of the day. About as long as the “rule of thumb” allows, and absolutely no longer than 8 hours (as I find that just cruel). Crating ensures dogs safety.

Q. We will be adopting a 3 year old Pit Bull this weekend. We have a 9 year old Dashaund already in the house. What should we do to help him adapt?
ANSWER : A. Congratulations on your new dog. I am assuming he has already been tested with your dog and vice versa? When you bring the new dog home, I suggest having both dogs on leash and meeting again outside of the home on neutral ground and taking a pack walk together once they have calmed down and seem okay. From there, once in the home you can keep the new dog leashed and just kinda let him wander around and explore the home. You may want to invest in a crate until he has proven to be house trained but keep the crate a positive space. Other things would be a new dog bed, dishes, toys, chew treats, etc. Also slowly transition him to your preferred food if it’s not the same he’s used to.

Q. My cat has eaten a dry Purina Cat Chow diet since 7 weeks old she is 14 yrs. She drinks cold water dripping from the bathtub faucet. Is this normal?
ANSWER : A. Dry cat food is fine for cats and can actually have a benefit of helping to keep their teeth clean. If she is 14 now, it may be a good idea to switch her to a senior diet in your brand if you have not already. Senior diets are usually tailored to address aging pet needs such as joint problems and weight gain from lessened activity.

Cats tend to enjoy running water sources to drink from rather than a bowl. If your cat enjoys this and you want to save money on your water bill, a cat fountain that recirculates the bowl water and keeps it dripping/streaming may interest her. If not, drinking from the tub is just fine if she enjoys it and it keeps her hydrated!

Q. I have a 10 year old pug overweight with dry skin and a 5 year old Yorkie with dry skin…..please advise me the very best dry dog food that. Can give
ANSWER : A. I am very partial to the foods made by Royal Canin. They do a lot of research on nutrition, and their foods have very high quality ingredients. They make a food called Small Breed which would be ideal for both a pug and a Yorkie. You can typically purchase that food from a vet, however they also make high quality diets that you can buy in stores like PetSmart. I’d also recommend purchasing a fish oil product that’s formulated for dogs. Dose according to label directions. The omega 3 fatty acids in fish oil is excellent for building healthy skin.
