New Dog Owner Here. Cross Breed: Great Pyrenees- Mountain Cur

Rahkii,
Congratulations on your new pup, and thank you for getting her out of a bad situation.
To answer your questions:
1) 7 months is not too late. The vet will give her all the necessary shots and a thorough physical exam.
2) Pyrs are a huge, majestic breed so a large size at a young age is to be expected. The vet will also be able to estimate the age. Make sure you get a good leash or harness for walking as they are very strong dogs.
3) Give her the amount of food she has been accustomed to. Increase the amount only if she looks skinny, and do it slowly. You will want to adjust the amount as she grows but don't go just by the amount printed on the dog food bags. Feed as high-quality a food as possible. It will avoid a lot of other health issues. I use www.dogfoodadvisor.com to check ratings of the food. Many vets are not very knowledgeable about nutrition and will often push the brands of foods the reps advertise.
5) 11 hours at a stretch is too long for a crate. A dog walker for those days is a good idea.
6) Its fine to leave her in the yard as long as it's securely fenced. I would supervise in the beginning to make sure she's not going to jump or dig her way out. You could put her on a long cable tie out if she has a tendency to escape, and till you get used to her habits.
7) it will take some time to potty train her. Consistency is key, as well as praise and reward when she gets it right. You can try taking her to a specific spot if you would prefer that. Mine goes where she likes but she has a few favored spots.
Pyrs are herding and guard dogs and take their job seriously so your pup may bark a lot.
Enjoy! These are gorgeous, good-natured dogs.

 

I didn't get insurance for my dogs, but it is certainly a good idea. Make sure you get one that does not have too many conditions, and get the extra rider for cancer. The costs for that or any major surgery can be catastrophic. Embrace and VPI are good companies to start with. Does your employer offer any benefits for pet insurance? Make sure the premiums make sense over paying out of pocket though.
I would be wary of dog parks till you have your pup better socialized. I have seen too many irresponsible owners at dog parks and the bigger dog automatically gets blamed.
Do you have a local Pyrenees rescue or club? You might be able to find some events you could take your pup to, like hikes. A Facebook group for the breed can be useful for general advice.
Your plan for potty training is perfect. She will soon adapt to a routine. When you see the vet make sure to do a stool test since puppies often have worms.
It's great if your dog doesn't bark! My friend had a Great Pyrenees and I just loved that dog!

 

COngratulations @Rakhii for getting a new pup. Really happy for a new addition in your family. I have a German Shepherd. She is 3 yrs now. Got it when she was 8 weeks old. Malstorm has addressed most of the points.
I’m just going to add on few.
* Check with the food brand. I give mine Red Fod naturals. Get large breed rice and chicken / turkey etc. Also when you are changing food brand you need to start with small quantities. I have cooked rice and boiled chicken for her. I give her boiled egg daily. When she is sick I give her yogurt rice. Surprisingly she enjoys so much . I avoid canned food as it is too much sodium. My friend cooks daily for hers. She enjoys human food. Whenever I make pasta , order pizza , chipotle or Indian snacks murrukku mixture she needs her small share.
* give her treats to train her to pee and poop. Like mine will stand near the door and bark. I can differentiate the bark sound. My friend’s will ring the bell. Every time say pee /poop and wait for her to complete. Give her a treat that way she will be able to relate. Until she gets trained , you need the crate after that she will be big for that. Also crate can be useful when you are traveling and staying in a hotel. Mine no longer stays in her crate.
* Rescue dogs are more affectionate and protective . My friend’s dog is cross of Great Pyrenees lab and German shepherd. They are big dogs. You just need to train them not to jump on anyone. Get a collar and a leash.
* talk with your husband and vet if you want to fix her ie in terms of reproduction. I fixed mine at 7 months. Now I regret . I should have let her be normal as I want to enjoy her babies.
* dog walker is good idea. Since I didn’t want dog walker I leave her in dog care / boarding for dogs when I need to travel. Sometimes my friend takes care. She enjoys at my friend’s place as she has her friend. You can try rover similar to Airbnb.
* I don’t allow mine to bedrooms. Too much hair everywhere so I trained her. Before going to bed when I sign off she will look at me till I go to my bedroom and then she goes to her bed.
* watch ceaser Milan show on NatGeo channel. He teaches how to train dogs.
* take her to dog park so she can socialize with other dogs.
* key is make her understand you,your husband and kids are leaders. This way she will not push you. Pet store offers 8 weeks class for 1st dog owners. Try to take the class.

I hope I didn’t scare you with too many information.

 

Don’t worry she will get better. Give her yogurt rice. Mine had worms too. Let me know if you need any help.

I forgot the following points.
Once a month bath is enough. During summers you may need to grow. Them. They have fur so no frequent baths. They shed during every season change. Keep combing their hair to control and trimming nails. After a bath give her tic medicine that will avoid her getting infected from small infections.

 

I subscribed to the Whole Dog Journal and they are an excellent resource for health and training tips. If you follow their Facebook page they often have articles on how to make raw and cooked homemade diets for your dog, health advice and general wellness tips.
I give my dog probiotics and kelp powder (Solid Gold Sea meal) with every meal, as well as fish oil (Grizzly wild pollock oil). It keeps her digestive tract healthy and the coat glossy. The most convenient way for me is just to order from www.chewy.com.
NaturVet Digestive Enzymes Plus Probiotic Dog & Cat Powder Supplement
We have ticks and heartworm here, so I give medicines for that every month, K9 Advantix Plus and Heartgard. I don't know if that is an issue in your place since Canada is much colder. Be wary if anyone suggests Trifexis for these problems. There have been several reports of dogs getting allergic reactions to Trifexis, fatal in some cases.
Also ask your vet about getting her spayed at the correct time. It will be better for her health.
