The aim of this study is to investigate the expenditure items and expenses for companion dogs and the appropriate considerations when choosing companion dog food for consumers who purchase dog food through the internet. The survey subjects consisted of 39 males (6.8%) and 532 females (93.2%), and it was found that most women purchase dog food through the internet. According to the age of dog owner, 184 (32.2%) were in their 20s and 241 (42.2%) in their 30s and 146 (25.6%) in their 40s or older. According to the age of the dogs, 200 (35%) were under 3 years old, 202 (35.4%) over 8 years old, and 169 (29.6%) were between 4 and 7 years old. The most preferred ingredient was chicken, regardless of dogs' owner or the dogs' age. Spending less than 100,000 won was most frequency reported, regardless of dog owner and the age of the dog, and major dog food was reported to be purchased in the order of online shopping malls and animal hospitals. In order to improve health function, it was determined that improvement of skin and hair is the most important, and next, was improvement of tooth bone formation and digestibility. When choosing food for companion dogs, nutritional composition of all the products was the most important consideration, followed by brand products with recognition, color, smell, shape, functional improvement products, and price of the products. Therefore, when developing a new product for companion dog food, consideration must be given not only to the nutritional components of all products, but also the brands, color, odor, shape, nutritional balance, functional improvement and price.

This study investigated the effects of dietary Ptecticu tenebrifer powder and canned mixtures on protein digestibility by different breeds of companion dogs (15 Bichons, 15 Malteses, 15 Chihuahuas and 15 Poodles). The mixtures were divided into Diet A, Diet B, Diet C, Diet D, and Diet E, which were supplied from five farms. Twenty-five grams each was mixed with 100 g of each canned food, and a total of 125 g was measured for each breed of dog. The result of component analysis of the mixtures showed the highest protein contents rather than dry matter, crude ash or crude fat. There were statistical significances (p<0.05) in all mixed feeds fed to bichon, maltese, chihuahua and poodle dog. Overall, protein digestibility by the breeds of dog ranged from 87.44% to 97.18%. Result of breed of dog comparison revealed that Diet E by poodle dog had the highest protein digestibility, and the lowest protein digestibility was observed in Diet C by Maltese. In conclusion, the use of dietary Ptecticu tenebrifer powder and canned mixtures did not only increased protein digestibility by different breeds of dog but also maintained normal manure properties.

The present study aimed to examine the effect of dietary Ptecticu tenebrifer powder mixtures as pet dogfeed ingredients on crude fat and ash digestibility. Three groups of feeds Feed A, Feed B, and Feed C supplied from three farms were fed to a total of 45 dogs. The dietary Ptecticu tenebrifer powder mixture were prepared by mixing 25 g of Ptecticu tenebrifer powder with 100 g of canned food. Feed A, Feed B, and Feed C containing dietary Ptecticu tenebrifer powder mixtures were fed to 15 dogs of each breed of bichon, poodle, and chihuahua that were divided into three groups following a completely randomized design. For measuring the crude fat and crude ash digestibility, manure of each dog breed from each group were collected. Crude fat digestibility was not statistically significant among the dog breeds fed with feed C (p>0.05), but overall there was a statistical difference between the feed and the group by dog breed (p<0.05). In terms of crude ash digestibility, the three types of feed showed differences with respect to dog breeds (p<0.05). However, the group with no significant difference was observed in Feed B by dog breed (p>0.05). In conclusion, feeding Ptecticu tenebrifer powder mixture to dog breeds had no positive effect on the crude fat and ash digestibility and can be used as pet dogfeed ingredients.

The effects of Queso Blanco cheese containing Bifidobacterium longum KACC 91563 was studied on the intestinal microbiota and short chain fatty acids (SCFAs) in healthy companion dogs. There were three experimental groups with five healthy dogs each: a control group, not fed with any cheese, and groups fed with Queso Blanco cheese with (QCB) or without B. longum KACC 91563 (QC) for 8 weeks. Fecal samples were collected 5 times before, during, and after feeding with cheese. Intestinal microbiota was analyzed using two non-selective agar plates (BL and TS) and five selective agar plates (BS, NN, LBS, TATAC, and MacConkey). SPME-GC-MS method was applied to confirm SCFAs and indole in dog feces. The six intestinal metabolites such as acetic, propionic, butyric, valeric, isovaleric acid and indole were identified in dog feces. Administration of B. longum KACC 91563 (QCB) for 8 weeks significantly increased the beneficial intestinal bacteria such as Bifidobacterium ($8.4{\pm}0.55$) and reduced harmful bacteria such as Enterobacteriaceae and Clostridium (p<0.05). SCFA such as acetic and propionic acid were significantly higher in the QCB group than in the Control group (p<0.05). In conclusion, this study demonstrates that administration of Queso Blanco cheese containing B. longum KACC 91563 had positive effects on intestinal microbiota and metabolites in companion dogs. These results suggest that Queso Blanco cheese containing B. longum KACC 91563 could be used as a functional food for companion animals and humans.

The companion animal related businesses are rapidly growing as the pet population increases in Korea. In this study, we analyzed the market trends of companion animal food and products to offer basic information that can be used in related policies and industries. The data were collected using Nielsen Korea's wholesale/retail distribution channels. As a result, in the case of companion dog food, PB products of domestic companies showed the highest market share with 24.6%, and the ratio of domestic companies(54.8%) was higher than that of import companies(45.2%). Domestic PB products also had the highest market share(16.5%) in companion cat food, however, the ratio of import companies(71.6%) was higher than that of domestic companies(28.4%). In the case of the market share of the companion animal products(toys, oral and bath supplies), Nosework mats from domestic companies were top ranked in the toy category(28.0%). Oral products(62.5%) and bath products(59.5%) from domestic companies were also having a higher market share than import companies. Our research may help domestic companion animal product companies to steadily increase market share and the amount of their export.

This study aimed to evaluate the differences in canine preferences for pet food terrine according to the processing method. As companion dogs, three male Spitz canines (average age 12 years, average weight 7 kg) and three male Spitz mix canines (average age 12 years, average weight 5 kg) were used in Experiment 1, whereas five male (average age 10 years, average weight 9 kg) and five female Shetland Sheepdogs (Sheltie, average age 10 years, average weight 8 kg) were used in Experiment 2, to evaluate their preferences and intake types. In both experiments, all dog categories mostly preferred 'meat' when it came to their first choice of food consumed, followed by 'vegetables', 'mixed eating', and 'vegetable leftover' last. This confirms means that canines are carnivores, and over time, choosing 'vegetables' or 'vegetable leftovers' as a secondary or alternate food source can be considered a natural process. When provided various terrines, canines in both experiments first ingested 'cooked' rather than 'freeze-dried' duck, chicken, beef, and pork terrines when selecting food at the start of feeding. For both experiments, most of the intake types using duck, chicken, beef, and pork terrine showed a preference for 'after consuming cooked terrine first and then intake freeze-dried' item. In conclusion, the reason for preferring cooked terrine can be attributed to the difference in the preparation cooking method of freeze-dried cooked terrine.

Numbers of companion animals and people rearing them are increasing in developed countries. As a result, businesses related to companion animals are becoming more advanced and specialized. Dogs have been cohabiting with humans as companions (pets) for thousands of years and, as a result, eat carbohydrate-rich foods similar to humans and maintain lives similar to their owners. Tight bonds between dogs and their owners are formed by sharing similar lifestyles, including a dwelling and food. Owners are responsible for their pets and treat them with emotional stability. Pets depend on their owners, although the food situation can cause stress. Since pet dogs are carnivorous in nature, providing pet dogs with a nutritionally balanced diet and functional materials is important for a healthy gut microbiome. Recently, the gut microbiota has become a research focus because it is associated with protection from harmful pathogens and immune regulation while maintaining physiological homeostasis. An abnormal gut microbiota is related to pathogenic processes and various gut, metabolic, mental, and neurological diseases. Additionally, pet dogs at risk of disease affect the health of their owners. Therefore, this review discusses the composition and diversity of the gut microbiota of dogs and the relationships between the gut microbiota and diseases.

Toxoplasmosis is caused by an obligate intracellular protozoan parasite; Toxoplasma gondii, which is one of the most important zoonotic parasite worldwide. In dogs, the sexual reproductive cycle of T. gondii is lacking, and the animals are not widely consumed as food, but they are vital in the mechanical transmission of the parasite. However, there is no present data on the exposure of stray dogs to T. gondii in Malaysia. The objective of this serological survey was to determine the prevalence of T. gondii antibodies (IgG) and associated factors in stray dogs in East and West Malaysia. Antibodies to T. gondii were determined in serum samples from 222 stray dogs from 6 different states in East and West Malaysia (Peninsular Malaysia) using an Indirect ELISA. The seroprevalence for T. gondii was 23.4% (Confidence interval: CI 17.8-29.2%). Stray dogs from Selangor and Kuala Lumpur had the highest seroprevalence (32.4%; CI 13.2-45.5%) and lowest in those from Penang and Kedah (12.5%; CI 1.3-23.5%). Gender and breed were not associated with T. gondii seropositivity. However, adult dogs were more likely to be seropositive for T. gondii (OR=2.89; CI 1.1-7.7) compared with younger dogs. These results revealed that T. gondii is prevalent in stray dogs in the studied areas in Malaysia, and indicative of the level of environmental contamination of this parasite especially in urban areas.

Oral malodor in companion animals is noticed by owners at first and it makes owners unpleasant. Therefore oral malodor affects the relationship between pet and owner. Oral malodor is produced by some putrefactive bacteria which putrefy proteins to volatile sulfur compounds (VSC) such as methyl mercaptan, hydrogen sulfide and dimethyl sulfide in the food remnants. And oral malodor is mostly consisted with these VSC. On oral examinations in dogs with oral malodor, it is common that plaque and calculus index were increased than normal dogs'. But organoleptic method is subjective to evaluate halitosis, in this study we measured VSC using organoleptic method and portable sulfide monitor to clarify the relationship between halitosis and periodontal disease in dogs with halitosis. And we found that plaque index and calculus index were significantly related with VSC (P<0.05, P<0.05) in measurement using Halimeter. However there was not significant relationship between gingivitis index and VSC. In conclusion, there was the significant, positive relationship between periodontal disease and halitosis.

Background: Use of prebiotics in companion animal nutrition is often considered advantageous over probiotics because of the ease of handling, ability to withstand processing and storage etc. While most of the studies on prebiotic use in dogs have been done with processed food as basal diet, the response in relation to homemade diet feeding is not very well explored. Methods: The study was conducted to evaluate the effects of dietary mannanoligosaccharide (MOS) supplementation on nutrient digestibility, hindgut fermentation, immune response and antioxidant indices in dogs. Ten Spitz pups were divided into two groups: control (CON) with no supplementation, and experimental (MOS) wherein the basal diet was supplemented with MOS at 15 g/kg diet. All dogs were fed on a home-prepared diet for a period of 150 days. The study protocol included a digestion trial, periodic blood collection and analysis for lipid profile and erythrocytic antioxidants. Immune response of the animals was assessed towards the end of the feeding period. Results: Results revealed no significant (P > 0.05) variations in palatability score, intake and apparent digestibility of nutrients between the groups. Faecal score, faeces voided, faecal pH, concentrations of ammonia, lactate and short-chain fatty acids were comparable (P > 0.05) between the two groups. Cell-mediated immune response, assessed as delayed-type of hypersensitivity response, was significantly higher (P < 0.05) in the MOS group. The percent of lymphocyte sub-populations CD4+ and ratio of CD4+:CD8+ were also significantly (P < 0.05) higher in MOS group. The serum IgG levels were similar (P > 0.05) in both the groups. Supplementation of MOS lowered (P < 0.05) serum total- and LDL- cholesterol levels, when compared with the control group. The erythrocytic antioxidant indices were similar (P > 0.05) between the two groups. Conclusions: The results indicated that supplementation of MOS at the rate of 15 g/kg in the diet of dog augmented the cell-mediated immune response and serum lipid profile without any influences on digestibility of nutrients, hindgut fermentation and antioxidants indices.
